6.6.2 I2C Output

The ZSSC3230 supports an I2C slave interface for digital output operation. The implementation of the interfaces is such that the available

commands (see section 6.7.2) and request codes for the ZSSC3230 are the same regardless on the interface type used.

Table 16). There is a general status byte, which is part of the ZSSC3230’s digital response on READ requests. Every response starts with a

status byte followed by the data word. The data word depends on the previous command. It is possible to read the same data more than once

if the read request is repeated. The next command invalidates any previous data.



Bit 7 is intentionally not assigned in order to allow for a 1 bit-length time.



Bit 6 indicates power: 1 if device is powered, 0 if not powered.



Bit 5 indicates whether the ZSSC3230 is busy. The data for the last command is not available yet. No new commands are processed if

the device is busy. It is “1” if the device is busy.
