Table 9.
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
STM32W108 interrupt system.
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 NRST-based reset.
