SPI Module

Functional

Function

When configured as peripheral for a multi-peripheral application, received data will have a right shift

Description

In multi-peripheral scenario, SPI controller first communicates with peripheral0 and then communicates with peripheral1. After finishing communication with peripheral1, the controller again communicates with peripheral0. During the second communication with peripheral0, received data of peripheral0 will have a right shift in the first frame. The peripheral0 is getting first data as 0x3B when the controller sent data 0x76.

Workaround

To support multi peripheral scenario CSCLR needs to be enabled at peripheral end to reset it's RX and TX the bit counters, when there is no active communication happening with that peripheral (CS of that peripheral will be disabled).
