Two of the four external interrupts, IRQA and IRQB, have fixed pin assignments. The other two external interrupts,
IRQC and IRQD, can use any GPIO pin. The GPIO_IRQCSEL and GPIO_IRQDSEL registers specify the GPIO
pins assigned to IRQC and IRQD, respectively. Table 7.4 shows how the GPIO_IRQCSEL and GPIO_IRQDSEL
register values select the GPIO pin used for the external interrupt.
In some cases, it may be useful to assign IRQC or IRQD to an input also in use by a peripheral, for example to
generate an interrupt from the slave select signal (nSSEL) in an SPI slave mode interface.
Refer to "11. Interrupt System" on page 190 for further information regarding the EM35x interrupt system.
7.9. Debug Control and Status
Two GPIO registers are largely concerned with debugger functions. GPIO_DBGCFG can disable debugger
operation, but has other miscellaneous control bits as well. GPIO_DBGSTAT, a read-only register, returns status
related to debugger activity (GPIO_FORCEDBG and GPIO_SWEN), as well a flag (GPIO_BOOTMODE) indicating
whether nBOOTMODE was asserted at the last power-on or nRESET-based reset.
