Table 28-21. SPI Pin Control Register 7 (SPIPC7) Field Descriptions (continued)
Bit Field Value Description
9 CLKPDIS CLK pull control disable. This bit disables pull control capability for the SPICLK pin if it is in input
mode, regardless of whether it is in functional or GIO mode.
0 Pull control on the CLK pin is enabled.
1 Pull control on the CLK pin is disabled.
8 ENAPDIS SPIENA pull control disable. This bit disables pull control capability for the SPIENA pin if it is in input
mode, regardless of whether it is in functional or GIO mode.
0 Pull control on the SPIENA pin is enabled.
1 Pull control on the SPIENA pin is disabled.
7-0 SCSPDIS SPICS pull control disable. This bit disables pull control capability for the SPICS pin if it is in input
mode, regardless of whether it is in functional or GIO mode.
0 Pull control on the SPICS pin is enabled.
1 Pull control on the SPICS pin is disabled.
28.3.14 SPI Pin Control Register 8 (SPIPC8)
NOTE: Register bits vary by device
Register bits 31:24 and 23:16 of this register reflect the number of SIMO/SOMI data lines per
device. On devices with 8 data-line support, all of bits 31 to 16 are implemented. On devices
with less than 8 data lines, only a subset of these bits are available. Unimplemented bits
return 0 upon read and are not writable.
NOTE: Default Register Value
The default values of these register bits vary by device. See your device datasheet for
information about default pin states, which correspond to the register reset values (see the
pin-list table).

Table 28-22. SPI Pin Control Register 8 (SPIPC8) Field Descriptions
Bit Field Value Description
31-24 SOMIPSEL SPISOMIx pull select. This bit selects the type of pull logic at the SOMIx pin.
Note: Bit 11 or bit 24 can be used to set pull-select for SPISOMI0. If a 32-bit write is
performed, bit 11 will have priority over bit 24.
0 Pull down on the SOMIx pin.
1 Pull up on the SOMIx pin.
