17.2 Control
The synchronous serial interface SIO0 is controlled by the low power consumption registers (POFFCR2), the
serial interface data buffer register (SIO0BUF), the serial interface control register (SIO0CR) and the serial interface
status register (SIO0SR).
Note 1: SIO0BUF is the data buffer for both transmission and reception. The last received data is read each time SIO0BUF is
read. If SIO0BUF has never received data, it is read as "0". When data is written into it, the data is treated as the transmit
data.
