Field ID #
In PSI5 initialization phase 2, 10-bit mode, the device transmits a sequence of sensor specific configuration and serial number
Offset and average self-test data will only be transmitted with sync pulse periods that guarantee the self-test phase1 & phase 2 will be complete prior to required
transmission. If sync pulse periods faster than this are used, ‘0’s will be transmitted instead of offset and/or average self-test data.
