[Description]
If the 1st operand (bit) contents have been set (1), they are cleared (0) and branched to the address specified
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.
When the 1st operand (bit) is PSW.bit, the corresponding flag contents are cleared (0).
[Description example]
BTCLR PSW.0, $356H;
When bit 0 (CY flag) of PSW is 1, the CY flag is cleared to 0 and branched to address
0356H (with the start of this instruction set in the range of addresses 02D4H to
03D3H).
