Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.

Operation mode transition
Please refer to the below figure of operation mode transition.
Power down mode is the smallest current consumption mode due to circuit is OFF. Please set this mode when
reducing current consumption. Measurement is not available in this mode, so the measurement is performed after
switching to standby mode.
In reset mode, regulator for internal blocks is active and measurement control block is reset. Register is initialized in
Reset mode. Measurement command is acceptable when “1” is written in “RSTB”
There are 2 measurement modes. One shot mode and Continuous mode. They are transferred from stand by mode.
Then, please set “AVE_NUM” register at the same time.
Please write “0x1400” when transferring to standby mode again.
In one shot mode, a single measurement is performed when “01” is written in “MODE”. After the measurement
completes, it is transferred to standby mode automatically. When “0x1400” is written before end of measurement,
mode is switched to standby immediately but pressure value is not updated.
Transition to the other measurement mode during measurement in one shot mode is forbidden.
In Continuous mode, when “10” is written in “MODE”, measurement starts and it continues until “0x1400” is
written.Transition to the other measurement mode from Continuous mode is forbidden.
