An additional start condition must be sent, which results in restoration of proper communication. • The restart condition—a falling SDA edge during data transmission when the CLK clock line is still high—creates the same situation. The next communication fails, and an additional start condition must be sent for correct communication. • A falling SDA edge is not allowed between the start condition and the first rising SCL edge. If using an I2C™ address with the first bit 0, SDA must be held low from the start condition through the first bit.

Accordingly, the master should sample the data on the rising edge of the SCLK signal. I2C/SPI DIAGNOSTIC FEATURES The P1J offers a full suite of diagnostic features to ensure robust system operation. The diagnostic states are indicated by a transmission of the status of the 2 MSBs of the bridge high byte data or by a saturated output at 3FFFH. STATUS BITS (2 MSB’S OF OUTPUT PACKAGE) Signal resolution Update rate Digital count at 0% pressure Digital count at 100% pressure DEFINITION 12 Bits (11 bits minimum for 0-2” H2O and 0-5 mBar range) 0.5 ms 1638 (10% of 214 counts or 0x666) 14746 (90% of 214 counts or 0x3999) When the two MSBs are 11, one of the following faults listed below is indicated. • Invalid EEPROM signature • Loss of bridge positive or negative • Bridge input short • Loss of bridge source • Loss of bridge sink All diagnostics are detected in the next measurement cycle and reported in the subsequent data fetch. Once a diagnostic is reported, the diagnostic status bits will not change unless both the cause of the diagnostic is fixed and a power-on-reset is performed.
