If USART does not operate in SPI Master Mode (MODE … 0xE):
0: No effect.
1: Drives the pin RTS to 1.
If USART operates in SPI Master Mode (MODE = 0xE):
RCS = 0: No effect.
RCS = 1: Releases the Slave Select Line NSS (RTS pin).
If USART does not operate in SPI Master Mode (MODE … 0xE):
0: No effect.
1: Drives the pin RTS to 0.
If USART operates in SPI Master Mode (MODE = 0xE):
FCS = 0: No effect.
FCS = 1: Forces the Slave Select Line NSS (RTS pin) to 0, even if USART is no transmitting, in order to address SPI slave
devices supporting the CSAAT Mode (Chip Select Active After Transfer).
0: No effect.
1: Drives the pin DTR to 1.
0: No effect.
1: Drives the pin DTR at 0.
0: No effect
1: Restart Time-out
0: No effect
1: Resets NACK in CSR.
0: No effect.
1: Resets ITERATION in CSR. No effect if the ISO7816 is not enabled.
