INSTRUCTION SET (Cont’d)
Conditional Branch. The branch instructions
achieve a branch in the program when the select-
ed condition is met.
Bit Manipulation Instructions. These instruc-
tions can handle any bit in data space memory.
One group either sets or clears. The other group
(see Conditional Branch) performs the bit test
branch operations.
Control Instructions. The control instructions
control the MCU operations during program exe-
cution.
Jump and Call. These two instructions are used
to perform long (12-bit) jumps or subroutines call
inside the whole program space.

e.
5 bit signed displacement in the range -15 to +16<F128M>
. Affected. The tested bit is shifted into carry.
ee.
8 bit signed displacement in the range -126 to +129
