Slave Mode

When the CPS-16/12/8 is configured as a slave, its physical device address is defined by 10 external pins,
ID[9:0]. The device can operate as either a 10-bit or 7-bit addressable device, as defined by an additional
external pin called ADS. If the ADS pin is tied to V

DD

(1.2V), then the device operates as a 10-bit

addressable device using ID[9:0]. If the ADS pin is tied to GND, then the device operates as a 7-bit
addressable device as defined by ID[6:0]
