Table 27-19. SPI Pin Control Register 5 (SPIPC5) Field Descriptions (continued)
Bit Field Value Description
9 CLKCLR SPICLK data out clear. This bit is only active when the SPICLK pin is configured as a general-
purpose output pin.
0 Read: The current value on SPICLK is 0.
Write: No effect.
1 Read: The current value on SPICLK is 1.
Write: Logic 0 is placed on SPICLK pin if it is in general-purpose output mode.
8 ENACLR SPIENA data out clear. This bit is only active when the SPIENA pin is configured as a general-
purpose output pin. A value of 1 written to this bit clears the corresponding ENABLEDOUT bit to 0.
0 Read: The current value on ENA is 0.
Write: No effect.
1 Read: The current value on ENA is 1.
Write: Logic 0 is placed on SPIENA pin if it is in general-purpose O/P mode.
7-0 SCSCLR SPISCSx data out clear. This bit is only active when the SPISCSx pin is configured as a general-
purpose output pin.
0 Read: The current value on SCSDOUTx is 0.
Write: No effect.
1 Read: The current value on SCSDOUTx is 1.
Write: Logic 0 placed on SPISCSx pin if it is in general-purpose output mode.
27.3.12 SPI Pin Control Register 6 (SPIPC6)
NOTE: Register bits vary by device
Register bits 31:24 and 23:16 of SPIPC0 to SPIPC9 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.
