(3) UARTAn control register 2 (UAnCTL2)
The UAnCTL2 register is an 8-bit register that selects the baud rate (serial transfer speed) clock of UARTAn.
This register can be read or written in 8-bit units.
Reset sets this register to FFH.
Caution Clear the UAnCTL0.UAnPWR bit to 0 or clear the UAnTXE and UAnRXE bits to 00 before
UAnCTL2
(n = 0, 1)
rewriting the UAnCTL2 register.
After reset: FFH
