MBAR Offset
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.
Address-triggered commands
0x15C (Read) Do not access.
0x16C UART Receiver FIFO
0x17C (Read) Do not access.
0x160 (Read) UART autobaud
0x164 (Read) UART autobaud
0x168 UART Transmitter FIFO
0x170 UART Fractional Precision
0x174 (Read) UART input port
