HSPI Chip Select Polarity

[metalphreak]

I have an SPI device that requires CS be active high rather than the default active low. Is there a configuration bit to change the polarity of the HSPI CS pin?

In spi_overlap.c|h of SDK 1.2.0:

Code: Select all

#define HSPI_FALLING_EDGE_SAMPLE()      SET_PERI_REG_MASK(SPI_USER(HSPI),  SPI_CK_OUT_EDGE)
#define HSPI_RISING_EDGE_SAMPLE()         CLEAR_PERI_REG_MASK(SPI_USER(HSPI),  SPI_CK_OUT_EDGE)
