DESCRIPTION
Low-Power, Low-Noise Multichannel
Load register X from program memory.
Clear X-reg.
A-reg = A-reg AND X-reg.
A-reg = A-reg OR X-reg.
A-reg = A-reg ADD X-reg.
X-reg = A-reg.
Shift left X-reg.
Shift right X-reg propagating sign bit.
X-reg = X-reg + 1.
X-reg = X-reg - 1.
X-reg = NOT X-reg.
Branch positive I-reg by amount in X-reg.
Branch not zero I-reg by amount in X-reg.
A-reg = CPU port-X.
CPU port-X = A-reg.
A-reg | M-reg = M-reg multiplied by
N-reg; register op code must be 3h.
