Description

PFIFOHx[15:8]

7 to 0

PFIFOLx[7:0][1]

The PFIFO stores the 12 latest pressure measurements. The PFIFO is implemented as a rolling buffer:

the most recent pressure measurement overwrites the oldest one. The INDFIFO index holds the value

of the last address written. Each entry shall occupy two bytes, high byte at first address and low byte at

second address, for a total of 24 bytes.

Where x = 1 to 12.

7 Limiting values

Limiting values are the extreme limits the device can be exposed to without permanently

damaging it. The device contains circuitry to protect the inputs against damage from high

static voltages; however, do not apply voltages higher than the values shown in Table 48.

Keep VIN and VOUT within the range VSS ≤ (VIN or VOUT) ≤ VDD.
