WRAM
Write to RAM
Description:
Write up to 128 RAM locations starting at the
beginning of the RAM bank specified as part of the instruction.
The number of bytes written is RAM is one plus the value of the
second byte.

CRAM
Copy RAM Bank to Registers
Description:
Copy the selected RAM Bank to the Configura-
tion Registers. This will overwrite all of the registers with the
data from the RAM bank.

CSRAMX
Calculate RAM Bank Checksum
Description:
Calculate the checksum of the selected RAM
Bank. The checksum is calculated as a sum of all the bytes with
the carry ignored. The ID,
DRDY
, and DIO bits are masked so
they are not included in the checksum.

CSARAMX
Description:
Calculate the checksum of all RAM Banks. The
checksum is calculated as a sum of all the bytes with the carry
ignored. The ID,
