Description
Silicon Mask Revision ID
The 4 bits read from this nibble reflect the silicon mask ID number. Specifically, the hex value in this nibble should be decoded
as the lower hex nibble in the hex numbers reflecting the ASCII characters in the range ‘A’ to ‘O’ .
Examples:
Bits 19-16 = 0001 = 1hex, therefore this value should be interpreted as 41 which is ASCII character A corresponding to silicon
mask revision A
Bits 19-16 = 1011 = Bhex, therefore the number is interpreted as 4B which is ASCII character K corresponding to silicon mask
revision K
The allowable range for this value is 1 to 15 which is interpreted as 41 to 4F or A to O)
Kernel Revision ID
This byte contains the hex number, which should be interpreted as an ASCII character indicating the revision of the kernel
firmware embedded in the on-chip Flash/EE memory.
Example: Reading 0x41 from this byte should be interpreted as A indicating a revision A kernel is on-chip.
Kernel Minor Revision number
For PreProduction Release, these bits refer to the Device’s Kernel Minor Revision Number
Part ID
These 16 LSBs will hold a 16-bit number, which should be interpreted as the part ID number. When used in conjunction with the
value in SYSSER0 i.e. the manufacturing lot ID, this number is a unique identifier for the part.
Read/Write
At power-on, this 32-bit register will hold the values of the part ID number, silicon mask revision number and kernel
revision number (bottom die only) as detailed below
Read/Write
At power-on, this 32-bit register will hold the kernel checksum

0x00000000 (Updated by kernel at power-on)
SYSCHK
0xFFFF0240
0x00000000(Updated by kernel at power-on)
