Operands:
S
: Source address
D
: Destination address for storing the result
n
: Bit number to test
Description:
1. The instruction checks the status of a designated bit (specified by
n
) in
S
and stores the
result in
D
2. If operands
S
,
n
use index F, then only 16-bit instruction is available.
3. Valid range of operand
n
:
n
=0~15 (16-bit),
n
=0~31 (32-bit)
Program Example:
1. When X0 = ON, and if the 15th bit of D0 = “1”, M0 is ON. But if the 15th bit of D0 is “0”, M0 is
OFF.
2. Once X0 is switched to OFF, M0 will stay at its previous state.
