Status bits, event bits and interrupt masks
The device detects and monitors events like sag and swell, tamper, energy register
overflow, power sign and errors, generating an interrupt signal on INTx pins when the
masked event is triggered.
When the event is triggered, the correspondent bit is set in two registers:
Live event register DSP_EV1,2
Status (also called interrupt) register DSP_SR1,2
To output the interrupt on INTx pins, the correspondent bit should be set in the interrupt
control mask register DSP_IRQ1,2
Live event register
In live event registers (DSP_EV1 and DSP_EV2), events are set and cleared by DSP at the
sampling rate DCLK = 7,8125 kHz.
