11.4.9 Memory bit manipulation instructions
SET1 mem.bit
Function: (mem.bit)
←
1 mem = D
7-0
: 00H to FFH, bit = B
1-0
: 0-3
Sets the bit specified by 2-bit immediate data bit at the address specified by 8-bit immediate data mem.
SET1 fmem.bit
SET1 pmem.@L
SET1 @H+mem.bit
Function: (bit specified by operand)
←
1
Sets the bit of the data memory addressed in the bit manipulation addressing mode (fmem.bit, pmem.@L, or
@H+mem.bit).
CLR1 mem.bit
Function: (mem.bit)
←
0 mem = D
7-0
: 00H to FFH, bit = B
1-0
: 0-3
Clears the bit specified by 2-bit immediate data bit at the address specified by 8-bit immediate data mem.
CLR1 fmem.bit
CLR1 pmem.@L
CLR1 @H+mem.bit
Function: (bit specified by operand)
←
0
Clears the bit of the data memory addressed in the bit manipulation addressing mode (fmem.bit, pmem.@L, or
@H+mem.bit).
SKT mem.bit
Function: Skip if (mem.bit) = 1
mem = D
7-0
: 00H to FFH, bit = B
1-0
: 0-3
Skips the next instruction if the bit specified by 2-bit immediate data bit at the address specified by 8-bit immediate
data mem is 1.
