Instruction Reference Manual

Description
Performs a logical AND operation between the byte in A and the byte in r (any of the registers A, B, C, D, E,
H, or L). The relative bits of each byte are compared (i.e., bit 0 of both bytes are compared, bit 1 of both bytes
are compared, etc.). The associated bit in the result byte is set only if both the compared bits are set. The result
is stored in A.
