SPI/I 2 C interrupt priority (1 = high, 0 = low).
Enables the energy metering interrupt (ADE). Set by the user.
Enables the RTC interval timer interrupt. Set by the user.
Enables the PSM power supply management interrupt. Set by the user.
Enables the SPI/I 2 C interrupt. Set by the user.
INTERRUPT PRIORITY
If two interrupts of the same priority level occur simultaneously, the polling sequence is observed (as shown in Table 81).
