• TXBUFE: TX Buffer Empty
0: SPI_TCR
(1)
or SPI_TNCR
(1)
has a value other than 0.
1: Both SPI_TCR
(1)
and SPI_TNCR
(1)
have a value of 0.
• NSSR: NSS Rising
0: No rising edge detected on NSS pin since last read.
1: A rising edge occurred on NSS pin since last read.
• TXEMPTY: Transmission Registers Empty
0: As soon as data is written in SPI_TDR.
1: SPI_TDR and internal shifter are empty. If a transfer delay has been defined, TXEMPTY is set after the completion of
such delay.
• SPIENS: SPI Enable Status
0: SPI is disabled.
1: SPI is enabled.
Note: 1. SPI_RCR, SPI_RNCR, SPI_TCR, SPI_TNCR are physically located in the PDC.
