Bit Data with Forced Status
When bits are designated, each bit is considered as one element.
The data for each element is expressed in one byte (8 bits). Bit 00 indicates
the specified bit data, and bit 01 indicates the forced status, When reading,
this one byte is returned.
Word Designations
When words are designated, each word is considered a single element. The
data for the element is expressed in two bytes. Bits 0 to 15 correspond to bits
0 to 15 of each word. When data is written, these two bytes are transmitted for
each word. When data is read, these two bytes are returned.
