9.3 Operation
9.3.1 Overview
The SCI supports serial data transfer in both asynchronous and synchronous modes.
The communication format depends on settings in the SMR as indicated in table 9-5. The clock
source and usage of the SCK pin depend on settings in the SMR and SCR as indicated in table 9-6.
