7.6.1.5 INT_STATUS Register (Address = 4h) [reset = 0h]
INT_STATUS is shown in Figure 30 and described in Table 12.
Return to Summary Table.
Interrupt status bits are set by events and cleared by bits in INT_CLEAR register. Status bits show if an event
has occurred since the last clearing. Start of an unmasked event sets the INT pin. If INT pin is cleared while an
event is active, it stays cleared until some other event starts.

7.6.1.6 INT_MASK Register (Address = 5h) [reset = 17h]
INT_MASK is shown in Figure 31 and described in Table 13.
Return to Summary Table.
Interrupt mask bits mask the event for INT pin. Interrupt status bits are not affected by mask bits.
