Controls pins AD[7:0].
When ‘0’, the pins are configured as outputs. The output values to the pins are set in POUT 7~0.
When ‘1’, the pins are high-Z. The input values to the pins are read in PIN 7~0.
Controls pin RDP1, RDN1 and RCLK1.
When ‘0’, the outputs are enabled on the pins.
When ‘1’, the pins are high-Z.
Controls pin RDP0, RDN0 and RCLK0.
When ‘0’, the outputs are enabled on the pins.
When ‘1’, the pins are high-Z.
Controls pin RDP3, RDN3 and RCLK3.
When ‘0’, the outputs are enabled on the pins.
When ‘1’, the pins are high-Z.
Controls pin RDP2, RDN2 and RCLK2.
When ‘0’, the outputs are enabled on the pins.
When ‘1’, the pins are high-Z.
Control pin ACK.
When ‘0’, the output is enabled on pin ACK.
When ‘1’, the pin is high-Z.
