Initial Power-up
All circuit elements are active. I2C port pins are high impedance and associated registers are cleared. The device then enters
standby mode.
Reading Coefficient Data
The user then typically accesses the part and reads the coefficient data. The main circuits within the slave device are disabled
during read activity. The coefficients are usually stored in the host microcontoller local memory but can be re-read at any time.
It is not necessary to read the values stored in the host microcontroller multiple times because the coefficients within a device
are constant and do not change. However, note that the coefficients will be different from device to device, and cannot be used
for another part.
Data Conversion
This is the first step that is performed each time a new pressure reading is required which is initiated by the host sending the
CONVERT command. The main system circuits are activated (wake) in response to the command and after the conversion
completes, the result is placed into the Pressure and Temperature ADC output registers.
The conversion completes within the maximum conversion time, tc (see Row 7, in the Operating Characteristics Table). The
device then enters standby mode.
Compensated Pressure Reading
After the conversion has been given sufficient time
