UAnCTL1 - UARTAn control register 1
The UAnCTL1 register is an 8-bit register used to select the input clock for the
UARTAn.
For details, see “UAnCTL1 - UARTAn control register 1“ on page 534.
UAnCTL2 - UARTAn control register 2
The UAnCTL2 register is an 8-bit register used to control the baud rate for the
UARTAn.
For details, see “UAnCTL2 - UARTAn control register 2“ on page 535.

Function
Parity selection
• This register is rewritten only when the UAnPWR bit = 0 or the UAnTXE bit =
• If “Reception with 0 parity” is selected during reception, a parity check is not
• When transmission and reception are performed in the LIN format, clear the
Specification of data character length of 1 frame of transmit/receive data
This register can be rewritten only when the UAnPWR bit = 0 or the UAnTXE bit =
