Re: HSPI Chip Select Polarity

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)

Not sure if this is for slave mode, though, as it's call...
