SPI Pin Control Register 6 (SPIPC6)
Bits 31:5
Reserved.
Reads are undefined and writes have no effect
Bit 4
SCS FUN: SPISCS function.
Determines whether the SPISCS pin is to be used as a general-purpose I/O
pin or as a SPI functional pin. If the slave SPISCS pin is in functional mode
and receives an inactive high signal, the slave SPI will place it’s output in
high-z and disable shifting.
0
=
SPISCS pin is a GPIO
1
=
SPISCS pin is a SPI functional pin
Bit 3
SOMI FUN: Slave out, master in function.
Determines whether the SPISOMI pin is to be used as a general-purpose
I/O pin or as a SPI functional pin.
0
=
SPISOMI pin is a GPIO
1
=
SPISOMI pin is a SPI functional pin
Bit 2
SIMO FUN: Slave in, master out function.
Determines whether the SPISIMO pin is to be used as a general-purpose
I/O pin, or as a SPI functional pin.
0
=
SPISIMO pin is a GPIO
1
=
SPISIMO pin is a SPI functional pin
Bit 1
CLK FUN: SPI clock function.
Determines whether the SPICLK pin is to be used as a general-purpose I/O
pin, or as a SPI functional pin.
0
=
SPICLK pin is a GPIO
1
=
SPICLK pin is a SPI functional pin
