ST6215C/ST6225C
INSTRUCTION SET (Cont’d)
Conditional Branch. Branch instructions perform
a branch in the program when the selected condi-
tion 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.

Jump and Call. These two instructions are used
to perform long (12-bit) jumps or subroutine calls
to any location in the whole program space.
