Register 0x0E (IRQ_MASK)
The IRQ_MASK register is used to enable (set register bit to 1) or disable (set register
bit to 0) interrupt events by writing the corresponding bit to the interrupt mask register.
If an interrupt will be enabled or disabled, it is recommended to read the interrupt status
register 0x0F (IRQ_STATUS) first to clear the history.
Register 0x0F (IRQ_STATUS)
The IRQ_STATUS register contains the status of the individual interrupts. A read
access to this register resets all interrupt bits.
By reading the register after an interrupt is signaled at IRQ pin, the reason for the
interrupt can be identified.
A detailed description of the individual interrupts can be found in Table 6-8.
