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.
