Field
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
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 locations.
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:
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.
Product of Multiply Low Byte.
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.
Working register (accumulator).
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).
8-bit Table Latch.
Top-of-Stack.
Program Counter.
Program Counter Low Byte.
Program Counter High Byte.
Program Counter High Byte Latch.
Program Counter Upper Byte Latch.
Global Interrupt Enable bit.
Watchdog Timer.
Time-out bit.
Power-Down bit.
ALU Status bits: Carry, Digit Carry, Zero, Overflow, Negative.
Optional.
Contents.
Assigned to.
Register bit field.
In the set of.
User-defined term (font is Courier New).
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).
