_Skip Group_ (5 usec.)
skp Y Operation Code 64
This group of instructions senses the state of various flip-flops and
switches in the machine. It does not require any reference to memory.
The address portion of the instruction selects the particular function
to be sensed. All members of this group have the same operation code.
_Skip on ZERO Accumulator_ (5 usec.)
sza Address 100
If the Accumulator is equal to plus ZERO (all bits are ZERO) the Program
Counter is advanced one extra position and the next instruction in the
sequence is skipped.
_Skip on Plus Accumulator_ (5 usec.)
spa Address 200
If the sign bit of the Accumulator is ZERO, the Program Counter is
advanced one extra position and the next instruction in the sequence is
skipped.
_Skip on Minus Accumulator_ (5 usec.)
sma Address 400
If the sign bit of the Accumulator is ONE, the Program Counter is
advanced one extra position and the next instruction in the sequence is
skipped.
_Skip on ZERO Overflow_ (5 usec.)
