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’.
If this instruction is executed on the TMR0 register (and, where applicable, d = 1), the prescaler will be cleared
if assigned.
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.
Some instructions are 2-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.
If the table write starts the write cycle to internal memory, the write will continue until terminated.
