The IDCODE register is missing from Table 2-12 (Debug Register Groups for 0x1B Register Numbers). Add IDCODE as the last entry in the table as follows:

Addition to Debug Register Groups for 0x1B Register Numbers (Table 2-12)

Register Name	Register Type	Direct Memory Address	Remarks
IDCODE	ID Code	0x18037A	Reset value 0xX27811CB

Following Figure 2-3 (PRFM Register Bit Descriptions), add the following new section describing the IDCODE register. (For a better idea of how this information will be formatted in its final form, see ADSP-TS201 TigerSHARC Processor Hardware Reference page 2-83).

Silicon Version and ID Code (IDCODE) Register

The IDCODE register indicates processor model ID and silicon version. The IDCODE register's reset value is 0xV278 11CB (where V is version).

The DMA request (DMARx asserted) signals indicated in Figure 5-18 and Figure 5-19 are not required. The following changes are needed:

• Remove the DMARx signal from both figures.
• The captions for these figures should change to:
  • Figure 5-18. FLYBY Write from I/O Device to SDRAM
  • Figure 5-19. FLYBY Read from SDRAM to I/O Device
• Change the first bullet in the description of figure 5-18 to:
  • Back to back quad-word writes from I/O Device to SDRAM occur.
• Change the first bullet in the description of figure 5-19 to:
  • Back to back quad-word reads from SDRAM to I/O Device occur.

In table 6-10 (Data Throughput Rates), the formulas in the last two rows need to be updated. Change from:

Autorefresh before read Read ... 1 word/17 cycle 6 + 2(tRP + tRAS + tRCD + CL) Autorefresh before write ... 1 word/11 cycle 2 + 2(tRP + tRAS + tRCD)

Change to:

Autorefresh before read Read ... 1 word/17 cycle (6 + 2tRP + tRAS + tRCD + CL) Autorefresh before write ... 1 word/11 cycle (2 + 2tRP + tRAS + tRCD)
