Serial-Data Output. DOUT outputs serial data from the data register. DOUT changes on the
falling edge of SCLK and is valid on the rising edge of SCLK. When CS is high, DOUT is
high impedance, unless APIO1 is programmed for SPI mode.
Serial-Clock Input. Apply an external serial clock to transfer data to and from the device.
When CS is high, SCLK is inactive unless APIO3 is configured for SPI mode. Then the input
on SCLK is level-shifted and output at APIO3.
Serial-Data Input. Data on DIN is clocked in on the rising edge of SCLK when CS is low.
When CS is high, DIN is inactive unless APIO2 is configured for SPI mode. Then the input
on DIN is level-shifted and output at APIO2.
Active-Low Chip-Select Input. Drive CS low to transfer data to and from the device. When
CS is high and APIO4 is configured for SPI mode, APIO4 is low.
Open-Drain Reset Output 1. RST1 remains low while DV
reprogrammed as a push-pull, active-high, or active-low Status register interrupt output.
Open-Drain Reset Output 2. RST2 remains low while DV
reprogrammed as a push-pull, active-high, or active-low Status register interrupt output.
