INC <Byte>
Function:
Increment
Description:
Increments the specified byte variable by 1. An original value of 0FFh overflows to 00h. Three addressing modes are
allowed for 8–bit operands: register, direct, or register–indirect.
Note :
When this instruction is used to modify an output Port, the value used as the original Port data is read from the output data latch, not the input
pins.
Example :
Register 0 contains 7Eh (011111110B) and on–chip RAM locations 7Eh and 7Fh contain 0FFh and 40h, respectively.
After executing the instruction sequence:
register 0 contains 7Fh and on–chip RAM locations 7Eh and 7Fh contain 00h and 41h, respectively.
