DEVICE POWER-UP AND ENABLE
Normal operation mode requirements:
1. The MODE1 and MODE2 signals need to be shorted together.
The following sequence describes the device power-up from shutdown. See
Figure 3 and Table 10 for timing
details.
Normal operation power-up requirements:
1. Apply power to the module through the VCC input.
2. Wait for the internal 32kHz clock to start-up and stabilize (t1).
3. Enable the module through the PWR_EN input.
4. Wait for the module to start-up and be ready (t2).
