16.3.1
The UART mode registers 1 (UMR1n) control configuration. UMR1n can be read or written when the
mode register pointer points to it, at RESET or after a
UCRn[MISC]. After UMR1n is read or written, the pointer points to UMR2n.

UMR1n, UMR2n, and UCSRn should be changed only after the receiver/transmitter is issued a software reset command. That
is, if channel operation is not disabled, undesirable results may occur.
This address is for factory testing. Reading this location results in undesired effects and possible incorrect transmission or
reception of characters. Register contents may also be changed.
