Slave Mode

When the CPS-1848 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

DD3

(3.3V), 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]

.

7.4.1

Signaling in Slave Mode

Communication with the CPS-1848 in Slave mode on the I

2

C bus supports the following cases:

1. Master device to CPS-1848:

a. Master device addresses the CPS-1848 as a slave
b. Master device (master-transmitter), sends data to the CPS-1848 (slave-receiver)
c. Master device terminates the transfer

2. CPS-1848 to Master device:

a. Master device addresses the CPS-1848 (slave)
b. Master device (master-receiver) receives data from the CPS-1848 (slave-transmitter)
c. Master device terminates the transfer.

Full signaling definition is defined in the I

2

C Specification. Standard waveforms are displayed in the following figures.
