356 /* I2C stop bit == data line goes from low to high while clock line is
357 * high - set data line low here, so the transition to the idle state
553 * Sets the idle state of the chip select pin. CS idles high by default.
556 * @idle - Set to 1 to idle high, 0 to idle low.
563 /* Chip select idles high, active low */
568 /* Chip select idles low, active high */
619 * SPI3 clock idles high, but needs to be set low before sending out
627 * SPI1 clock idles low, but needs to be set high before sending out
1013 * Sets the specified pin high.
1016 * @pin - Pin number to set high.
1025 retval = gpio_write(mpsse, pin, HIGH);
1112 * Checks if a specific pin is high or low. For use in BITBANG mode only.
1119 * Returns a 1 if the pin is high, 0 if the pin is low.
