16. Synchronous Serial Interface (SIO)
16.1 Configuration
receive data buffer that can automatically and continuously transfer up to 64 bits of data.
The TMP88FH41UG has a clocked-synchronous 8-bit serial interface. Serial interface has an 8-byte transmit and
Serial interface is connected to outside peripherl devices via SO, SI, SCK port.
This SIO and UART can not use simultaneously because their input/output ports are common.
