Bit addressing
This mode allows setting or clearing an individual bit without disturbing the other bits within
an 8-bit value of internal SRAM. Bit Addressing is only available for certain locations in 8032
DATA and SFR memory. Valid locations are DATA addresses 20h - 2Fh and for SFR
addresses whose base address ends with 0h or 8h. (Example: The SFR, IE, has a base
address of A8h, so each of the eight bits in IE can be addressed individually at address A8h,
A9h, ...up to AFh.) For example:
SETB AFh
; IE.
; Set the individual EA bit (Enable All ; Interrupts) inside the SFR register,
