stypeM
Slave type set by the master station
stypeM bit 7bit 6bit 5bit 4bit 3bit 2bit 1bit 0
Bits 7 and 6 : Reserved (0 at all times)
Bit 5 : SA (whether information and I/O from the master station to a slave
station are specified)
- When SA = 0, information and I/O from the master station to a
slave station are not specified.
- When SA = 1, information and I/O from the master station to a
slave station are specified
Bit 4 : ST (whether a type of I/O from the master station to a slave station is
specified)
- When ST = 0, no type of I/O from the master station to a slave
station is specified.
- When ST = 0, a type of I/O from the master station to a slave
station is specified.
NOTE
The setting of bits 3 to 1 is valid when ST = 1.
Bit 3 : DW (data write)
Set DW = 1 to enable data write service.
Bit 2 : DR (data read)
Set DR = 1 to enable data read service.
Bit 1 : DO (output)
