Instruction spec (5) of PIC16 series


Instruction set

INCFIncrement f
Form [label]INCFf, d
( label is omitable, shows SPACE code )
Operands f : Register file addesss ( 00(00h) to 127(7Fh) )
d : Destination select ( 0 or 1 )
Operation It adds 1 to the contents of the f register.
d = 0 : store result in W
d = 1 : store result in f
(EX)
Operation When the result is 0, it sets 1 to the Z flag.
When the result is not 0, it sets 0 to the Z flag.
Instruction
cycles
1 cycle


INCFSZIncrement f, Skip if 0
Form [label]INCFSZf, d
( label is omitable, shows SPACE code )
Operands f : Register file addesss ( 00(00h) to 127(7Fh) )
d : Destination select ( 0 or 1 )
Operation It adds 1 to the contents of the f register.
d = 0 : store result in W
d = 1 : store result in f
In case of the result of the addition is 0, it changes the following instruction into the NOP and executes it. (It executes the instruction of the present address +2.)
FlagNo change

IORLWInclusive OR literal with W
Form [label]IORLWk
( label is omitable, shows SPACE code )
Operandsk : literal field ( 00(00h) to 255(FFh) )
Operation It executes the logic OR operation of the literal data and the contents of the W register.
(EX)
Flag When the result is 0, it sets 1 to the Z flag.
When the result is not 0, it sets 0 to the Z flag.

IORWFInclusive OR W with f
Form [label]IORWFf, d
( label is omitable, shows SPACE code )
Operands f : Register file addesss ( 00(00h) to 127(7Fh) )
d : Destination select ( 0 or 1 )
Operation It executes the logic OR operation of the contents of the f register and the W register.
d = 0 : store result in W
d = 1 : store result in f
(EX)
Flag When the result is 0, it sets 1 to the Z flag.
When the result is not 0, it sets 0 to the Z flag.
