[Description example]
BTCLR
• If the 1st operand (bit) contents have been set (1), they are cleared (0) and branched to the address specified
• When the 1st operand (bit) is PSW.bit, the corresponding flag contents are cleared (0).
BTCLR PSW.0, $356H; When bit 0 (CY flag) of PSW is 1, the CY flag is cleared to 0 and branched to address
bit =PSW.bit
by the 2nd operand.
If the 1st operand (bit) contents have not been set (1), no processing is carried out and the subsequent
instruction is executed.
