Bits [3:0] SC_RATELIN: The linear component (LIN) of the clock rate in the equation:
SPI status register (SCx_SPISTAT)
Address offset: 0xC840 (SC1_SPISTAT) and 0xC040 (SC2_SPISTAT)
Reset value:
Serial clock linear prescaler register (SCx_RATELIN)
Address offset: 0xC860 (SC1_RATELIN) and 0xC060 (SC2_RATELIN)
Reset value:
Bit 1 SC_SPIPHA: Clock phase configuration: clear this bit to sample on the leading (first edge) and
Bit 0 SC_SPIPOL: Clock polarity configuration: clear this bit for a rising leading edge and set this bit
Bit 3 SC_SPITXIDLE: This bit is set when both the transmit FIFO and the transmit serializer are
Bit 2 SC_SPITXFREE: This bit is set when the transmit FIFO has space to accept at least one byte.
Bit 1 SC_SPIRXVAL: This bit is set when the receive FIFO contains at least one byte.
Bit 0 SC_SPIRXOVF: This bit is set if a byte is received when the receive FIFO is full. This bit is
