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).
bit3:2
Writing "00"
Writing "01"
Writing "10"
Writing "11"
[bit1] CKS: Clock select bit
This bit selects a serial clock from the external clock or the UART/SIO dedicated baud rate generator.
bit1
Writing "0"
Writing "1"
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).
bit0
Writing "0"
Writing "1"
Note:
During data transmission or reception, do not modify the settings of the UART/SIO serial
mode control register 1 ch. n (SMC1n).
