CRC Byte 0.
A write to this register initiates a 16-bit CRC of one 256-byte block of EPROM mem-
ory. The byte written to CRC0 is the upper byte of the 16-bit address where the CRC
will begin. The lower byte of the beginning address is always 0x00. When complete,
the 16-bit result will be available in CRC1 (MSB) and CRC0 (LSB). See Section
“13.4. Program Memory CRC” on page 74.
A write to this register initiates a 32-bit CRC on the entire program memory space.
The CRC begins at address 0x0000. When complete, the 32-bit result is stored in
CRC3 (MSB), CRC2, CRC1, and CRC0 (LSB). See Section “13.4. Program Memory
CRC” on page 74.
