26.3.2
The UMR2n registers control UART module configuration. UMR2n can be read or written when
the mode register pointer points to it, which occurs after any access to UMR1n. UMR2n accesses
do not update the pointer.

Transmitter ready-to-send. Controls negation of UnRTS to automatically terminate a message
transmission. Attempting to program a receiver and transmitter in the same channel for UnRTS
control is not permitted and disables UnRTS control for both.
