CHAPTER 22 UART/SIO
22.7 Registers
[bit3:2] CBL[1:0]: Character bit length control bits
These bits select the character bit length.
The setting of these bits is valid in both clock asynchronous mode (UART) and clock synchronous mode
(SIO).
[bit1] CKS: Clock select bit
This bit selects a serial clock from the external clock or the UART/SIO dedicated baud rate generator.
Note: Setting this bit to "1" forcibly disables the output of the UCKn pin. The external clock cannot be used
in clock asynchronous mode (UART).
[bit0] MD: Operation mode select bit
This bit selects an operation mode from the clock asynchronous mode (UART) or the clock synchronous
mode (SIO).
Note:
During data transmission or reception, do not modify the settings of the UART/SIO serial
mode control register 1 ch. n (SMC1n).
