CHAPTER 14 UART, SERIAL I/O INTERFACE (SIO), INPUT CAPTURE MODULE, AND OUTPUT COMPARE
This section describes the overview of the UART, the configuration and functions of
registers, and UART operation.
■ Overview of the UART
The UART is a serial I/O port that is used to perform asynchronous (start-stop synchronization) or CLK
synchronous communication. The UART has the features described below. The MB91F355A/355A/354A/
F356B/F357B have a 5 channel UART.
The MB91F353A/351A/352A/353A have a 4 channel UART.
