SBAS171B

STOPC

Stop Continuous

Description: Ends the continuous data output mode.

Operands:

None

Bytes:

Encoding:

0000 1111

Data Transfer Sequence:

RREG

Read from Registers

Description: Output the data from up to 16 registers starting

with the register address specified as part of the instruction.

The number of registers read will be one plus the second byte.

If the count exceeds the remaining registers, the addresses will

wrap back to the beginning.

Operands:

r, n

Bytes:

Encoding:

0001 rrrr xxxx nnnn

Data Transfer Sequence:

Read Two Registers Starting from Register 01H (MUX)

RRAM

Read from RAM

Description: Up to 128 bytes can be read from RAM starting

at the bank specified in the op code. All reads start at the

address for the beginning of the RAM bank. The number of

bytes to read will be one plus the value of the second byte.

Operands:

a, n

Bytes:

Encoding:

0010 0aaa xnnn nnnn

Data Transfer Sequence:

Read Two RAM Locations Starting from 20H

CREG

Copy Registers to RAM Bank

Description: Copy the 16 control registers to the RAM bank

specified in the op code. Refer to timing specifications for

command execution time.

Operands:

Bytes:

Encoding:

0100 0aaa

Data Transfer Sequence:

Copy Register Values to RAM Bank 3

CREGA

Copy Registers to All RAM Banks

Description: Duplicate the 16 control registers to all the

RAM banks. Refer to timing specifications for command

execution time.

Operands:

None

Bytes:

Encoding:

0100 1000

Data Transfer Sequence:
