AND1 CY, fmem.bit
AND1 CY, pmem.@L
AND1 CY, @H+mem.bit
Function: CY <– CY ^ (bit specified in operand)
ANDs the content of the carry flag with the bit in data memory specified by bit manipulation addressing
(fmem.bit, pmem.@L, @H+mem.bit), then sets the result in the carry flag.
OR1 CY, fmem.bit
OR1 CY, pmem.@L
OR1 CY, @H+mem.bit
Function: CY <– CY ¦ (bit specified in operand)
ORs the content of the carry flag with the bit in data memory specified by bit manipulation addressing
(fmem.bit, pmem.@L, @H+mem.bit), then sets the result in the carry flag.
XOR1 CY, fmem.bit
XOR1 CY, pmem.@L
XOR1 CY, @H+mem.bit
Function: CY <– CY ¦ (bit specified in operand)
Exclusive-ORs the content of the carry flag with the bit in data memory specified by bit manipulation
addressing (fmem.bit, pmem.@L, @H+mem.bit), then sets the result in the carry flag.
11.4.10 Branch Instructions
BR addr
Function: For the µPD750008 PC
12-0
<– addr
addr = 0000H-1FFFH
Branches to the address specified by the immediate data addr.
This instruction is an assembler pseudo instruction, and the assembler automatically replaces this
instruction with the BR !addr instruction, BRCB !caddr instruction, or BR $addr instruction as required at
assembly time.
