CHAPTER 9. INSTRUCTION SET
SKF mem. bit
Function: Skit if (mem. bit) = 0; mem = D
7
to D
0
: 00H to 3FH, bit = B
1
to B
0
: 0 to 3
If the bit specified by 2-bit immediate data bit of the address specified by 8-bit immediate data mem is 0,
skips the next instruction.
SKF fmem. bit
Function: Skip if (bit specified by operand) = 0
If the contents of the data memory bit specified by bit manipulation addressing (fmem. bit) is 0, skips the
next instruction.
SKTCLR fmem. bit
Function: Skip if (bit specified by operand) = 1 then clear
If the data memory bit specified by bit manipulation addressing (fmem. bit) is 1, skips the next instruction
and clears that bit to 0.
AND1 CY, fmem. bit
Function: CY
←
CY
∧
(bit specified by operand)
ADDs the contents of the carry flag and the contents of the data memory bit specified by bit manipulation
addressing (fmem. bit) and sets the result into the carry flag.
OR1 CY, fmem. bit
Function: CY
←
CY
∨
(bit specified by operand)
ORs the contents of the carry flag and the contents of the data memory bit specified by bit manipulation
addressing (fmem. bit) and sets the result into the carry flag.
XOR1 CY, fmem. bit
Function: CY
←
CY
∨
(bit specified by operand)
Exclusive-ORs the contents of the carry flag and the contents of the data memory bit specified by bit
manipulation addressing (fmem. bit) and sets the result into the carry flag.
