SIO0CON is a special function register (SFR) to control the synchronous serial port.
[Description of Bits]
•
S0EN (bit 0)
The S0EN bit is used to specify start of synchronous serial communication. Writing a “1” to this bit starts 8-/16-bit
data communication. This bit is set to “0” automatically when 8-/16-bit data communication is terminated.
The S0EN bit is set to “0” at a system reset.
S0EN Description
0 Stops communication. (Initial value)
1
Starts communication
