The TMP19A61 contains two Serial Bus Interface (SBI) channels; CH0 and CH1 that operate
identically (only CH0 is described here). The Serial Bus Interfaces have the following two operation
modes.
The following table shows the programming required to put the SBI in each operating mode.

In the I
clock-synchronous 8-bit SIO mode, the SBI is connected to external devices via PE7 (SCK), PE5
(SO) and PE6 (SI).
