ORL CY,<src-bit>
Function:
Logical–OR for bit variables
Description:
Sets the CY flag if the Boolean value is a logical 1; leaves the CY flag in its current state otherwise. A slash (”/”)
preceding the operand in the assembly language indicates that the logical complement of the addressed bit is used as
the source value, but the source bit itself is not affected.
Example :
Set the CY flag if and only if P1.0 = 1, ACC.7 = 1 or OV = 0.

FLAGS :
Hex Code in:
