Interface Description
Interrupts
Interrupt requests can be read from the composite interrupts register (0x0008; see register description, page 148).
There is also a corresponding block interrupt masks register (0x000C; see register description, page 149). Any
unmasked request will cause the INT pin to go low. GPIO interrupt functionality is shown in Figure 30.
