JB bit51,rel JB bit,rel
Function:
Jump if bit set
Description:
If the specified bit is a one, jump to the address specified; otherwise proceed with the next instruction. The branch
destination is computed by adding the signed relative displacement in the third instruction byte to the PC, after
incrementing the PC to the first byte of the next instruction. The bit tested is not modified.
Example :
Input Port 1 contains 11001010B and the accumulator contains 56h (01010110B). After the instruction sequence:
program execution continues at label LABEL2.
