UART Modules
Writing control bytes into the appropriate registers controls the UART operation. A list of UART module
registers and their associated addresses is shown in
For the registers described in this section, the numbers above the register description represent the bit
position in the register. The register description contains the mnemonic for the bit. The values as shown in
the following tables are the values of those register bits after a hardware reset. A value of U indicates that
the bit value is unaffected by reset. The read/write status is shown in the last line.
15.4.1
The UMR1 controls some of the UART module configuration. This register can be read or written at any
time and is accessed when the mode register pointer points to UMR1. The pointer is set to UMR1 by
RESET or by a set pointer command using the control register. After reading or writing UMR1, the pointer
points to UMR2.

This address is used for factory testing and should not be read. Reading this location results in undesired effects and possible
incorrect transmission or reception of characters. Register contents can also be changed.

UART 0
Mode Register 1 (UMR1n)
All UART module registers are accessible only as bytes. The contents of the
mode registers (UMR1 and UMR2), clock-select register (UCSR), and the
auxiliary control register (UACR) bit 7 should be changed only after the
receiver/transmitter is issued a software RESET command—i.e., channel
operation must be disabled. Be careful if the register contents are changed
during receiver/transmitter operations because unpredictable results can
occur.
