MSPM0G3519: UART 9 bit data mode

Part Number: MSPM0G3519

Tool/software:

Hi Support,

My assigned focus customer has asked if there is any way to have the UARTS on the MSPM0G3519 support 9 data bits?

From the TRM, I see 4 x 8 FIFOs so didn't know if there were any way to 'fake' a 9 data bit mode?

Can the address bit be used as a 9th data bit?

It would appear that some of the comp has a true 9 bit FIFO.

Thanks!

Blake

    Hi Blake,
    The UART module allows a 9-bit Address Mode. The address qualifier is at the location of the parity bit. The Userguide's 18.2.3.10 9-Bit UART Mode section provides more information. We currently don't have any examples in the SDK for this mode.
