10 Error Reporting and Interrupt Control
10.1 Interrupt Control Registers
10.1.2 Interrupts Via External GP[7:0]
10.1.2.1 GPIO Interrupt Pending Register
The GPIO interrupt pending register stores detected interrupts via the GP[7:0] signals. The user can clear specific
pending bits by writing 1 to that bit (write 1 to clear). Interrupts via these signals are maskable via the GPIO inter-
rupt enable register.
