Operation:
Description:
Examples:
1. Assuming that bit location 30H.2 in the RAM has a current value of "0", the following
2. You can use BITS in the same way to manipulate a port address bit:
Bit Set
dst.b
This instruction sets the specified bit within the destination without affecting any other bits in the
destination. BITS can manipulate any bit that is addressable using direct or indirect addressing
modes.
instruction sets the second bit of location 30H to "1".
