LP-MSPM0G3507: How to use UART with DMA to receive data of variable length

MCU-PLUS-SDK-AM263PX: UART DMA to receive variable length unstructured data

TollMan
Intellectual 485 points
Part Number: MCU-PLUS-SDK-AM263PX

Tool/software:

This question is related to a prior thread for a different MCU:

(1) LP-MSPM0G3507: How to use UART with DMA to receive data of variable length - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums

Basically, I want to receive unstructured data, trigger a Read Transfer Interrupt (to call UartRxHandler()) every N bytes. If a new frame is received that is less than N bytes, I need to trigger the UartRxHandler() to read the 'partial frame'. Presumably, the partial frame event would be triggered by an 'idle time' after the last byte was received.

How can this be done on AM263PX?
