MPC5744P configure UART Rx as Idle low

[ajaysrinivasann]

Hello,

Is there any way to configure UART Rx as Idle low? I want to read a stream of bytes from an external device which sends the information as 8bits, 1 stop bit, no parity and idle low. Thanks in advance. I am using the Devkit for MPC5744p with PB[3] configured for UART.

Regards

Ajay

Hi,

There is only a possibility to invert signal within a SIUL module. You should set IMCRx[INV] bit.

Within the LINFlex module you can only invert the received data (payload) using the LINFlex_GCR[RDLIS] bit.
