Exclusive OR Literal to W
Note 1: The 9th bit of the program counter will be forced to a '0' by any instruction that writes to the PC except for
GOTO
.
(Section 4.5)
2: When an I/O register is modified as a function of itself (e.g.
MOVF GPIO, 1
), the value used will be that value
present on the pins themselves. For example, if the data latch is '1' for a pin configured as input and is driven
low by an external device, the data will be written back with a '0'.
3: The instruction
TRIS f
, where f = 5, 6, or 7 causes the contents of the W register to be written to the tristate
latches of GPIO. A '1' forces the pin to a hi-impedance state and disables the output buffers.
4: If this instruction is executed on the TMR0 register (and, where applicable, d = 1), the prescaler will be cleared
(if assigned to TMR0).
