About reception error in UART mode of serial array unit

Last Updated:01/16/2018

Question:

Will a transfer end interrupt be generated when a reception error occurs while using the serial array unit (SAU) in UART mode?
Will the data that is received when an error occurs be stored in the serial data register mn (SDRmn)?

Answer:

A transfer end interrupt will be generated even if a reception error occurs.
Since the data received when the error occurred is stored in the serial data register mn (SDRmn), the SDRmn register must be read out and the read data must be disregarded. Also, judge each error flag in order to execute the appropriate processing according to your system.
