Register Descriptions
14.3.11 UART Divider Upper/Lower Registers (UDUn/UDLn)
The UDUn registers (formerly called UBG1n) holds the MSB, and the UDLn registers
(formerly UBG2n) hold the LSB of the preload value. UDUn and UDLn concatenate to
provide a divider to BCLKO for transmitter/receiver operation, as described in
Section 14.5.1.2.1, “BCLKO Baud Rates.”

Change-of-state.
0 UIPCRn[COS] is not selected.
1 Change-of-state occurred on CTS and was programmed in UACRn[IEC] to cause an interrupt.
Reserved, should be cleared.
Delta break.
0 No new break-change condition to report. Section 14.3.5, “UART Command Registers (UCRn),”
1 The receiver detected the beginning or end of a received break.
RxRDY (receiver ready) if UMR1n[FFULL/RxRDY] = 0; FIFO full (FFULL) if UMR1n[FFULL/RxRDY]
= 1. Duplicate of USRn[FFULL/RxRDY]. If FFULL is enabled for UART0 or UART1, DMA channels 2
or 3 are respectively interrupted when the FIFO is full.
Transmitter ready. This bit is the duplication of USRn[TxRDY].
0 The transmitter holding register was loaded by the CPU or the transmitter is disabled. Characters
1 The transmitter holding register is empty and ready to be loaded with a character.
The minimum value that can be loaded on the concatenation of
UDUn with UDLn is 0x0002. Both UDUn and UDLn are
write-only and cannot be read by the CPU.

loaded into the transmitter holding register when TxRDY = 0 are not sent.
