OPCODE FIELD DESCRIPTIONS
RAM access bit
a = 0: RAM location in Access RAM (BSR register is ignored)
a = 1: RAM bank is specified by BSR register
ACCESS = 0: RAM access bit symbol
BANKED = 1: RAM access bit symbol
Bit address within an 8-bit file register (0 to 7)
Bank Select Register. Used to select the current RAM bank.
Destination select bit;
d = 0: store result in WREG,
d = 1: store result in file register f.
Destination either the WREG register or the specified register file location
8-bit Register file address (0x00 to 0xFF)
12-bit Register file address (0x000 to 0xFFF). This is the source address.
12-bit Register file address (0x000 to 0xFFF). This is the destination address.
Literal field, constant data or label (may be either an 8-bit, 12-bit or a 20-bit value)
Label name
The mode of the TBLPTR register for the Table Read and Table Write instructions
Only used with Table Read and Table Write instructions:
No Change to register (such as TBLPTR with Table reads and writes)
Post-Increment register (such as TBLPTR with Table reads and writes)
Post-Decrement register (such as TBLPTR with Table reads and writes)
Pre-Increment register (such as TBLPTR with Table reads and writes)
The relative address (2’s complement number) for relative branch instructions, or the direct
address for Call/Branch and Return instructions
Product of Multiply high byte (Register at address 0xFF4)
Product of Multiply low byte (Register at address 0xFF3)
Fast Call / Return mode select bit.
s = 0: do not update into/from shadow registers
s = 1: certain registers loaded into/from shadow registers (Fast mode)
Unused or Unchanged (Register at address 0xFE8)
W = 0: Destination select bit symbol
Working register (accumulator) (Register at address 0xFE8)
Don't care (0 or 1)
The assembler will generate code with x = 0. It is the recommended form of use for compatibility
with all Microchip software tools.
21-bit Table Pointer (points to a Program Memory location) (Register at address 0xFF6)
8-bit Table Latch (Register at address 0xFF5)
Top-of-Stack
Program Counter
Program Counter Low Byte (Register at address 0xFF9)
Program Counter High Byte
Program Counter High Byte Latch (Register at address 0xFFA)
Program Counter Upper Byte Latch (Register at address 0xFFB)
Global Interrupt Enable bit
Watchdog Timer
Time-out bit
Power-down bit
