TABLE 27-1: OPCODE FIELD DESCRIPTIONS
Field Description
a RAM access bit:
a = 0: RAM location in Access RAM (BSR register is ignored)
a = 1: RAM bank is specified by BSR register
bbb Bit address within an 8-bit file register (0 to 7)
BSR Bank Select Register. Used to select the current RAM bank
C, DC, Z, OV, N ALU Status bits: Carry, Digit Carry, Zero, Overflow, Negative
d Destination select bit:
d = 0: store result in WREG
d = 1: store result in file register f
dest Destination: either the WREG register or the specified register file location
f 8-bit register file address (00h to FFh), or 2-bit FSR designator (0h to 3h)
f
s
12-bit register file address (000h to FFFh). This is the source address
f
d
12-bit register file address (000h to FFFh). This is the destination address
GIE Global Interrupt Enable bit
k Literal field, constant data or label (may be either an 8-bit, 12-bit or a 20-bit value)
label Label name
mm The mode of the TBLPTR register for the table read and table write instructions
Used only 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)
n The relative address (2’s complement number) for relative branch instructions or the direct address for
Call/Branch and Return instructions
PC Program Counter
PCL Program Counter Low Byte
PCH Program Counter High Byte
PCLATH Program Counter High Byte Latch
PCLATU Program Counter Upper Byte Latch
PD
Power-Down bit
PRODH Product of Multiply High Byte
PRODL Product of Multiply Low Byte
s 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)
TBLPTR 21-Bit Table Pointer (points to a program memory location)
TABLAT 8-Bit Table Latch
TO
Time-out bit
TOS Top-of-Stack
u Unused or Unchanged
WDT Watchdog Timer
WREG Working register (accumulator)
x 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
z
s
7-bit offset value for Indirect Addressing of register files (source)
z
d
7-bit offset value for Indirect Addressing of register files (destination)
{ } Optional argument
[text] Indicates Indexed Addressing
(text) The contents of text
