3.14 Serial Channels (SIO)
The TMP92CF30 include 2 serials I/O channel (SIO0 and SIO1). For channels either UART
mode (Asynchronous transmission) or I/O interface mode (Synchronous transmission) can be
selected. And, SIO0 and SIO1 include data modulator that supports the IrDA 1.0 infrared data
communication specification.
In mode 1 and mode 2, a parity bit can be added. Mode 3 has a wakeup function for making
the master controller start slave controllers via a serial link (A multi-controller system).
Figure 3.14.1 is block diagrams for each channel.
Each channel is compounded mainly prescaler, serial clock generation circuit, receiving
buffer and control circuit, transmission buffer and control circuit.
Each channel can be used independently.
Each channel operates in the same fashion except for the following points; hence only the
operation of channel 0 is explained below.
