Baud Rate Generator Double-Speed Mode Select

0 (0): Baud rate generator outputs the clock with single frequency.

1 (1): Baud rate generator outputs the clock with doubled frequency.

Asynchronous Mode Base Clock Select

0 (0): Selects 16 base clock cycles for 1-bit period.

1 (1): Selects 8 base clock cycles for 1-bit period.

Asynchronous Mode Extended Base Clock Select

0 (0): Clock cycles for 1-bit period is decided with combination be-tween CCR2.BGDM and CCR2.ABCS.

1 (1): Baud rate is 6 base clock cycles for 1-bit period and the clock of a double frequency is output from the baud rate generator.

Bit rate setting

Bit Modulation Enable

0 (0): Bit rate modulation function is disabled.
