The description of the sequencer status (SQSTAT) register is incorrect. The following bit descriptions in SQSTAT need to change:
| Bit No. | Error | Correction |
|---|---|---|
| Bit 24 | Incorrectly identified as BTBMOD:0 | Change to BTBEN |
| Bit 25 | Incorrectly identified as BTBMOD:1 | Change to BTBLK |
| Bit 28 | Incorrectly identified as BTBLK | Change to Reserved |
| Bit 29 | Incorrectly identified as BTBEN | Change to Reserved |
Remove all references to the non-existent BTBMOD bit field.

The documentation incorrectly states that:
In USER mode with the SYS_REG_WE strap pin disabled at reset, the SDRCON register can be written only once after hardware reset and cannot be changed during system operation - subsequent writes to SDRCON are ignored.
To write to the SDRCON register (and SYSCON register) more than once after reset in USER mode, enable the SYS_REG_WE strap pin during reset. In SUPERVISOR mode, SYSCON and SDRCON have no write restrictions.
In SUPERVISOR mode, SDRCON is write once after reset if the SYS_REG_WE strap pin is disabled. If the SYS_REG_WE strap pin is enabled, there are no write restrictions for SDRCON in SUPERVISOR mode. SDRCON can never be written in USER mode regardless of the SYS_REG_WE strap pin setting.

In the description paragraph for the IDCODE register, change the reference to the EMUCTL register (in the second sentence) to IDCODE.
In Figure 2-45 (IDCODE Register Bit Descriptions), change ID31-28 to IDCODE31-28, and change ID27-0 to IDCODE27-0.
In footnote 1 of Figure 2-45 (IDCODE Register Bit Descriptions), change ID27-0 to IDCODE27-0.

Add the following paragraph to the Cycle Counter (CCNTx) Registers section:
To keep both of the cycle counter registers coherent between the two write accesses, a shadow register is used to temporarily hold the value written for the CCNT0 register. This temporary value is not written into the actual CCNT0 register until a write has also been issued to the CCNT1 register. So, the CCNT0 and CCNT1 registers must also be written to in the same order as they are read; write to CCNT0 first, then write to CCNT1 to allow for coherent writes of these registers.

The last two lines of the third paragraph incorrectly state:
If the timer is active (TMRxRN bit is set), writing a value to the TMRINxH/L register has no effect. Writing a different value to TMRINxH/L while the timer is operating changes the initial value after the next expiration of the timer (when TMRINxH/L value is copied again to the timer).
If the timer is active (TMRxRN bit is set), writing a value to the TMRINxH/L register has an immediate effect. Writing a different value to TMRINxH/L while the timer is operating changes current timer operation, and the value is used as the initial value after the next expiration of the timer (when TMRINxH/L value is copied again to the timer).

Use the following two sections to replace the "Vector Interrupt" section. Also, add a cross reference from the KERNEL entry in Table 6-1 (page 6-19) to the new "Kernel Interrupt section.
Vector Interrupt
The vector interrupt is a general purpose interrupt. The interrupt is triggered by writing a value to the VIRPT register, or equivalently writing a value to the corresponding location in the interrupt vector table. Unlike typical interrupts, this unique functionality identifies the address of the associated interrupt service routine dynamically at the time the interrupt is triggered. The VIRPT register is accessible to both externally and internally generated write transactions.
Kernel Interrupt
The kernel interrupt is distinct, but functionally identical to the vector interrupt. Like the vector interrupt, the address of the interrupt service routine is defined by the value written to the KERNEL register or the corresponding location in the vector interrupt table. This functionality, in conjunction with the associated priority level of the kernel interrupt (the kernel interrupt is the lowest priority interrupt), makes it well suited for utilization in an RTOS supporting a pre-emptive scheduling paradigm. However, this does not preclude the kernel interrupt from being utilized in other applications. As with the VIRPT register, the KERNEL register is accessible to externally and internally generated write transactions.

In Table 7-5 (DMA Channel Priority), the AutoDMA Register names are missing from the Channel column. These table cells should be shown as follows:

The documentation erroneously states that:
In USER mode, SYSCON is write once after reset, unless the SYS_REG_WE strap pin is enabled. In Supervisor mode, SYSCON has no write restrictions.
In SUPERVISOR mode, SYSCON is write once after reset if the SYS_REG_WE strap pin is disabled. If the SYS_REG_WE strap pin is enabled, there are no write restrictions for SYSCON in SUPERVISOR mode. SYSCON can never be written in USER mode regardless of the SYS_REG_WE strap pin setting.

In paragraph 2, that last two sentences incorrectly state the SDRAM sizes per bank and the total amount of SDRAM supported by the TS201. The following two sentences should be changed from:
The SDRAM interface provides a glueless interface with standard SDRAMs—6M bits, 64M bits, 128M bits, 256M bits, and 512M bits. The TigerSHARC processor directly supports a maximum of 64M words x 32 bits of SDRAM per bank for a total of 856M words.
