UART Modules
23.3.2
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.

Parity type. PM and PT together select parity type (PM = 0x) or determine whether a data or address character is
transmitted (PM = 11).
