UMR1n, UMR2n, and UCSRn must be changed only after the receiver/transmitter is issued a software reset command. If
operation is not disabled, undesirable results may occur.
Reading this register results in undesired effects and possible incorrect transmission or reception of characters. Register
contents may also be changed.
