10. Synchronous Serial Interface (SIO)
10.1 Configuration
INTSIO
SIOCR1
interrupt
The serial interfaces connect to an external device via SI, SO, and
When these pins are used as serial interface, the output latches for each port should be set to "1".
Control circuit
Note: Set the register of port correctly for the port assigned as serial interface pins.
Internal clock
input
For details, see the description of the input/output port control register.
