Correct COM parameters for LPC 'Periph_DMIC' example

I have built the 'periph_dmic' example from LPC_Open for the LPC54114. This example streams numerical data from the UART to a terminal, as opposed to the 'i2s_periph_dmic' example which streams audio data out of the Wolfson CODEC. I think I have my terminal (PuTTY) correctly configured, but I'm still getting a rolling screen of garbled characters.


My PuTTY settings are:

Baud rate: 750000

Data bits: 8

Stop bits: 1

Parity: None

Flow control: XON/XOFF

I can tell that the program is running as when I 'tap' near the mic I can see the quantity of garbled characters increase/decrease.

Wanted to see if I'm missing something with the settings.
