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 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.
5: If the Table Write starts the write cycle to internal memory, the write will continue until terminated.
