Rabbit 2000/3000 Microprocessor
Description
Resets bit b (any of the bits 0, 1, 2, 3, 4, 5, 6, or 7) of the data whose address is:
•
held in HL, or
•
the sum of the data in IX and a displacement d, or
•
the sum of the data in IY and a displacement d.
The bit is reset by performing a logical AND between the selected bit and its complement.
