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 Chapter 11, Interrupt System, 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.

GPIO Signal Assignment Summary

The GPIO signal assignments are shown in Table 7-5.
