Disable Modem functionality on UART1

zabian — Wed, 04 Apr 2018 15:56:18 GMT

How can we disable the modem functionality on UART1 on the LPC408X_LPC177X_LPC178X series.

We think this is causing communications issues. We don't have any problems with the other UART ports.

Thanks.

Thank you for your interest in NXP Semiconductor products and

for the opportunity to serve you.

Clearing the MCR register will disable the modem function.

Have a great day,

TIC
