As the processing method when the bit device (X, Y, M) is specified, 1-bit processing
and 16-bit processing using digit designation processing are available.

When a PLC instruction is used, the device used as the target of operation processing
is one bit (one point) of bit device, and multiple bits cannot be specified.

When a basic or application instruction is used, the bit device used as the target of
operation processing may have to be specified by digit designation. When the
instruction whose processing unit is 16 bits is specified by this digit designation, up to
16 points can be specified in units of four points.

(a) When there is digit designation on the source (S) side, the numerical values

that can be handled as the source data are as indicated in Table 3.6.
