0: The USART does not filter the receive line.
1: The USART filters the receive line using a three-sample filter (1/16-bit clock) (2 over 3 majority).
0: NACK is sent on the ISO line as soon as a parity error occurs in the received character (unless INACK is set).
1: Successive parity errors are counted up to the value specified in the MAX_ITERATION field. These parity errors generate a
NACK on the ISO line. As soon as this value is reached, no additional NACK is sent on the ISO line. The flag ITERATION is
asserted.
0: The NACK is generated.
1: The NACK is not generated.
0: 16x Oversampling.
1: 8x Oversampling.
0: The USART does not drive the CLK pin.
1: The USART drives the CLK pin if USCLKS does not select the external clock CLK.
0: CHRL defines character length.
1: 9-bit character length.
If USART does not operate in SPI Mode (MODE … 0xE and 0xF):
MSBF = 0: Least Significant Bit is sent/received first.
MSBF = 1: Most Significant Bit is sent/received first.
If USART operates in SPI Mode (Slave or Master, MODE = 0xE or 0xF):
CPOL = 0: The inactive state value of SPCK is logic level zero.
CPOL = 1: The inactive state value of SPCK is logic level one.
CPOL is used to determine the inactive state value of the serial clock (SPCK). It is used with CPHA to produce the required
clock/data relationship between master and slave devices.
