M0564
6.22 UART Interface Controller (UART)
6.22.1 Overview
The M0564 series provides three channels of Universal Asynchronous Receiver/Transmitters
(UART). The UART controller performs Normal Speed UART and supports flow control function.
The UART controller performs a serial-to-parallel conversion on data received from the peripheral
and a parallel-to-serial conversion on data transmitted from the CPU. Each UART controller
channel supports ten types of interrupts. The UART controller also supports IrDA SIR, LIN and
RS-485 function modes and auto-baud rate measuring function.
