... In order to switch between the measurement modes necessary first to stop the active mode before activating the new one by writing 0x00 in to OPERATION register. This will instruct SCP1000 to cancel the current operation (SCP1000 enters in to standby mode). After writing 0x00 to OPERATION register and before new measurement mode is activated there should delay. Instead of the 50 ms delay, OPSTATUS register can be read. If OPSTATUS bit in OPSTATUS register is ‘ ...

... For more details of pressure data bit level description, see section 3.2 (Table 12). Pressure data is presented in integer format. When operating within the nominal operation range (30…120 kPa) the output of the SCP1000 changes between 120000 and 480000. The output is converted from decimal format to [Pa] as follows: ...

... Once the mode has been started the only interface activity required is periodic reading of the output pressure and temperature registers (in applications where the temperature is not needed the output temperature reading can be omitted), see section 2.2.1.1. SCP1000 operation parameters in high resolution measurement mode are presented in Table 5 below. Table 5. SCP1000 operation parameters in high resolution mode. ...
Page 14
... In high speed measurement mode pressure and temperature are measured continuously the conversion time is shortened at the cost of output resolution. This allows an increased output refresh rate of approximately 9 Hz. SCP1000 operation parameters in high speed measurement mode are presented in Table 6 below. Table 6.

... In order to decrease further the current consumption in cases where there are long time intervals between the measurements, SCP1000 has a built in power down mode, which can be activated through the PD pin. SCP1000 will stay in power down mode as long as the PD signal is high. In power down mode every digital output pin of SCP1000 tristates. ...

... SCP1000 is done using MOSI, MISO, SCK and CSB. CSB selects the chip on multi-chip SPI bus, SCK is the serial data clock, MOSI is the data line from master to slave (Master Out Slave In) and MISO is data line from slave to master (Master In Slave Out). SCP1000 is configured to SPI slave mode (see Figure 8). ...
