Debug Control and Status
GPIO Signal Assignment Summary
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.
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.
The GPIO signal assignments are shown in Table 7-5.
