UART Module

Category

Functional

Function

RTOUT counter not counting as per expectation in IDLE LINE MODE

Description

In IDLE LINE MODE in UART, RTOUT counter gets stuck, even when the line is IDLE and FIFO has some elements. This means that RTOUT interrupts will not work in IDLE LINE MODE.
In case of an address mismatch, RTOUT counter is reloaded when it sees toggles on the Rx line.
In case of a multi-responder scenario this could lead to an indefinite delay in getting an RTOUT event when communication is happening between the commander and some other responder.

Workaround

Do not enable RTOUT feature when UART module is used either in IDLELINE mode/multi-node UART application.
