31.3.11 UART Baud Rate Generator Registers (UBG1n/UBG2n)
The UBG1
n
registers hold the MSB, and the UBG2
n
registers hold the LSB of the preload value. UBG1
n
and UBG2
n
concatenate to provide a divider to the internal bus clock for transmitter/receiver operation,
Section 31.4.1.2.1, “Internal Bus Clock Baud Rates
NOTE
The minimum value loaded on the concatenation of UBG1
n
with UBG2
n
is
0x0002. The UBG2
n
reset value of 0x00 is invalid and must be written to
before the UART transmitter or receiver are enabled. UBG1
n
and UBG2
n
are write-only and cannot be read by the CPU.
31.3.12 UART Input Port Register (UIPn)
The UIP
n
registers show the current state of the U
n
CTS input.
