SIO0MOD0 is a special function register (SFR) to set mode of the synchronous serial port.
[Description of Bits]
Note:
• Do not change any of the SIO0MOD0 register settings during transmission/reception.
• When the synchronous serial port is used, the tertiary functions of GPIO must be set. For the tertiary functions of Port
4, see Chapter 20, “Port 4”.
SIO0MOD0
Initial value
The S0DIR is used to select LSB first or MSB first.
The S0MD1 and S0MD0 bits are used to select transmit, receive, or transmit/receive mode of the synchronous serial
port.
The S0LG bit is used to specify the bit length of the transmit/receive buffer, 8-bit or 16-bit length.
The S0LG bit is set to “0” at a system reset.
