I
PC<9:0>
PG<1:0>
PC<11:10>
None
GOTO is an unconditional branch. The 10-bit immediate value is loaded into PC bits <9:0>.
GOTO is a two-cycle instruction.

Syntax:
Operands:
Increment R
INCR R, d

63
d

[0,1]
R + 1
dest
Z
The contents of register ‘R’ are incremented. If ‘d’ is 0 the result is placed in the ACC register.
If ‘d’ is 1 the result is placed back in register ‘R’.

R + 1
dest, skip if result = 0
None
The contents of register ‘R’ are incremented. If ‘d’ is 0 the result is placed in the ACC register.
If ‘d’ is the result is placed back in register ‘R’.
If the result is 0, then the next instruction, which is already fetched, is discarded and a NOP is
executed instead making it a two-cycle instruction.

Operation:
S/W Interrupt
INT

PC
None
Interrupt subroutine call. First, return address (PC+1) is pushed onto the stack. The address
002h is loaded into PC bits <10:0>.

ACC or R
dest

Inclusive OR the ACC register with register ‘R’. If ‘d’ is 0 the result is placed in the ACC
register. If ‘d’ is 1 the result is placed back in register ‘R’.
