I2C TIMING DIAGRAM
Note
There are three adjustments to the I2C implementation compared with the original I2C™ protocol:
• Sending a start-stop condition without any transitions on the CLK line (no clock pulses in between) creates a communication error for the next
communication, even if the next start condition is correct and the clock pulse is applied. 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.

Output Packet with Positive Edge Sampling
Packet = [ {S(1:0), B(13:8)}, {B(7:0)}, {T(10:3)}, {T(2:0),xxxxx}] Where
S(1:0) = Status bits of packet (normal, command, busy, diagnostic)
B(13:8) = Upper 6 bits of 14-bit bridge data
B(7:0) = Lower 8 bits of 14-bit bridge data
T(10:0) = NOT corrected temperature data (mask out or terminate read early)

SPI TIMING DIAGRAM
Note
The MISO line is setup to change state on the falling edge of the SCLK clock. 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)

DEFINITION

14746 (90% of 214 counts or 0x3999)
Digital count at 0% pressure
Digital count at 100% pressure
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.
