Notes

MSb

LSb

Note 1: When a Port register is modified as a function of itself (e.g., MOVF PORTB, 1, 0), 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’.

2: If this instruction is executed on the TMR0 register (and where applicable, ‘d’ = 1), the prescaler will be cleared

if assigned.

3: 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.

4: Some instructions are two-word instructions. The second word of these instructions will be executed as a NOP

unless the first word of the instruction retrieves the information embedded in these 16 bits. This ensures that all

program memory locations have a valid instruction.
