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.
2
Reading this register results in undesired effects and possible incorrect transmission or reception of characters. Register
contents may also be changed.
