GOTO Unconditional Branch
Syntax: [
label ] GOTO k
Operands: 0  k  2047
Operation: k  PC<10:0>
PCLATH<4:3>  PC<12:11>
Status Affected: None
Encoding:
10 1kkk kkkk kkkk
Description:
GOTO is an unconditional branch. The
eleven bit immediate value is loaded
into PC bits <10:0>. The upper bits of
PC are loaded from PCLATH<4:3>.
GOTO is a two-cycle instruction.
Words: 1
Cycles: 2
Example
GOTO THERE
After Instruction
PC = Address THERE
INCF Increment f
Syntax: [
label ] INCF f,d
Operands: 0  f  127
d  [0,1]
Operation: (f) + 1  (dest)
Status Affected: Z
Encoding:
00 1010 dfff ffff
Description:
The contents of register 'f' are
incremented. If 'd' is 0, the result is
placed in the W register. If 'd' is 1, the
result is placed back in register 'f'.
Words: 1
Cycles: 1
Example
INCF CNT, 1
Before Instruction
CNT = 0xFF
Z=0
After Instruction
CNT = 0x00
Z=1
INCFSZ Increment f, Skip if 0
Syntax: [
label ] INCFSZ f,d
Operands: 0  f  127
d  [0,1]
Operation: (f) + 1  (dest), skip if result = 0
Status Affected: None
Encoding:
00 1111 dfff ffff
Description:
The contents of register 'f' are
incremented. If 'd' is 0, the result is
placed in the W register. If 'd' is 1, the
result is placed back in register 'f'.
If the result is 0, the next instruction,
which is already fetched, is discarded.
A NOP is executed instead making it a
two-cycle instruction.
Words: 1
Cycles: 1(2)
Example
HERE INCFSZ CNT, 1
GOTO LOOP
CONTINUE •
•
•
Before Instruction
PC = address HERE
After Instruction
CNT = CNT + 1
if CNT= 0,
PC = address CONTINUE
if CNT 0,
PC = address HERE +1
IORLW Inclusive OR Literal with W
Syntax: [
label ] IORLW k
Operands: 0  k  255
Operation: (W) .OR. k  (W)
Status Affected: Z
Encoding:
11 1000 kkkk kkkk
Description:
The contents of the W register are
OR’ed with the eight bit literal 'k'. The
result is placed in the W register.
Words: 1
Cycles: 1
Example
IORLW 0x35
Before Instruction
W = 0x9A
After Instruction
W= 0xBF
Z=1
