• TXBUFE: TX Buffer Empty
(1)
(1)
0 = SPI_TCR
or SPI_TNCR
has a value other than 0.
(1)
(1)
1 = Both SPI_TCR
and SPI_TNCR
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.
