Description

Tests bit b (any of the bits 0, 1, 2, 3, 4, 5, 6, or 7) of the byte whose address is in HL.

The Z flag is set if the tested bit is 0, reset the bit is 1.

This is a chained-atomic instruction, meaning that an interrupt cannot take place between this instruction and the instruction following it.
