Bit 2
SIMODIR.
SPISIMO direction.
Controls the direction of the SPISIMO pin when it is used as a general-
purpose I/O pin. If the SPISIMO pin is used as a MibSPI functional pin, the I/
O direction is determined by the MASTER bit (SPICTRL2.3).
0 =
SPISIMO pin is an input
1 =
SPISIMO pin is an output
Bit 1
CLKDIR.
SPICLK direction.
Controls the direction of the SPICLK pin when it is used as a general-purpose
I/O pin. In functional mode, the I/O direction is determined by the CLKMOD
bit (SPICTRL2.5).
0 =
SPICLK pin is an input
1 =
SPICLK pin is an output
Bit 0
ENADIR.
SPIENA direction.
Controls the direction of the SPIENA pin when it is used as a general-purpose
I/O. If the SPIENA pin is used as a functional pin, then the I/O direction is
determined by the CLKMOD bit (SPICTRL2.5).
0 =
SPIENA pin is an input
1 =
SPIENA pin is an output
