Note 1:

When an I/O register is modified as a function of itself ( e.g., MOVF PORTB, 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’.

If this instruction is executed on the TMR0 register (and, where applicable, d = 1), the prescaler will be cleared if assigned

to the Timer0 Module.

If Program Counter (PC) is modified or a conditional test is true, the instruction requires two cycles. The second cycle is

executed as a NOP.

Note:

Additional information on the mid-range instruction set is available in the PICmicro Mid-Range MCU Family

Reference Manual (DS33023).
