10 Error Reporting and Interrupt Control
10.1 Interrupt Control Registers
Table 73. Interrupt Control Register Map
10.1.1 Interrupts Via External FG[7:0] Registers
10.1.1.1 FGIO Interrupt Pending Register
The FGIO interrupt pending register stores detected interrupts via the FG[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 FGIO inter-
rupt enable register.
