STOPC Stop Continuous
Description: Ends the continuous data output mode.
Operands: None
Bytes: 1
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: 2
Encoding: 0001 rrrr xxxx nnnn
Data Transfer Sequence:
Read Two Registers Starting from Register 01
H
(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

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: a
Bytes: 1
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
