Reset Value:
• RTSDIS/RCS: Request to Send Disable/Release SPI Chip Select
0: No effect.
1: Drives the pin RTS to 1.
RCS = 0: No effect.
RCS = 1: Releases the Slave Select Line NSS (RTS pin).
• RTSEN/FCS: Request to Send Enable/Force SPI Chip Select
0: No effect.
1: Drives the pin RTS to 0.
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).
• RETTO: Rearm Time-out
0: No effect
1: Restart Time-out
• RSTNACK: Reset Non Acknowledge
0: No effect
1: Resets NACK in CSR.
