Rabbit 2000 - RES B,(HL)

110 Rabbit 2000/3000 Microprocessor
Description
Resets bit b (anyofthebits0,1,2,3,4,5,6,or7)ofthedatawhoseaddressis:
• heldinHL, 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.
