0: The USART can not recover from a clock drift.
1: The USART can recover from clock drift (only available in 16x oversampling mode).
0: Zeroes are encoded as zero-to-one transitions, and ones are encoded as a one-to-zero transitions.
1: Zeroes are encoded as one-to-zero transitions, and ones are encoded as a zero-to-one transitions.
0: The receiver preamble pattern detection is disabled.
1 - 15: The detected preamble length is RX_PL x bit period
