(2) UARTAn control register 1 (UAnCTL1)
The UAnCTL1 register is an 8-bit register that selects the UARTAn base clock.
This register can be read or written in 8-bit units.
Reset sets this register to 00H.
Caution Clear the UAnCTL0.UAnPWR bit to 0 before rewriting the UAnCTL1 register.
(n = 0 to 2)
UAnCTL1
After reset: 00H
Remark
Note Only UARTA0 is valid; setting UARTA1 and UARTA2 is prohibited.
