WRAM

Write to RAM

Description: Write up to 128 RAM locations starting at the

beginning of the RAM bank specified as part of the instruc-

tion. The number of bytes written is RAM is one plus the value

of the second byte.

Operands:

a, n

Bytes:

Encoding:

0110 0aaa xnnn nnnn

Data Transfer Sequence:

Write to Two RAM Locations starting from 10H

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.

Operands:

Bytes:

Encoding:

1100 0aaa

Data Transfer Sequence:

Copy RAM Bank 0 to the Registers

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.

Operands:

Bytes:

Encoding:

1101 0aaa

Data Transfer Sequence:

Calculate Checksum for RAM Bank 3

CSARAMX Calculate the Checksum

for all RAM Banks

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, DRDY and DIO bits are masked so they are

not included in the checksum.

Operands:

None

Bytes:

Encoding:

1101 1000

Data Transfer Sequence:

CSRAM

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. All bits are included in the checksum

calculation, there is no masking of bits.

Operands:

Bytes:

Encoding:

1110 0aaa

Data Transfer Sequence:

Calculate Checksum for RAM Bank 2

CSREG

Calculate the Checksum of

Registers

Description: Calculate the checksum of all the registers. 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.

Operands:
