This section identifies the requirements for initializing the surrounding modules when the general-purpose interface module is to be used for the first time after a device reset. This initialization of surrounding modules is based on the environment and integration of the general-purpose interface. For more information, see GPIO Environment, and GPIO Integration.
| Surrounding Modules | Comments |
|---|---|
| LPSC0 | Module reset must be enabled. For more information about the module configuration, see Reset. |
| LPSC3 | Module reset must be enabled. For more information about the module configuration, see Reset. |
| LPSC9 | Module reset must be enabled. For more information about the module configuration, see Reset. |
| PLLCTRL0 | Interface and functional clocks must be enabled. For more information about the module configuration, see Clocking. |
| WKUP_PLLCTRL0 | Interface and functional clocks must be enabled. For more information about the module configuration, see Clocking. |
| WKUP_RC_OSC_12M | Interface and functional clocks must be enabled. For more information about the module configuration, see Clocking. |
| GPIOMUX_INTRTR0 | Device INTCs must be configured to enable the interrupt request generation. For information about enabling GPIOMUX_INTRTR0 interrupts, see Interrupts. |
| WKUP_GPIOMUX_INTRTR0 | Device INTCs must be configured to enable the interrupt request generation. For information about enabling WKUP_GPIOMUX_INTRTR0 interrupts, see Interrupts. |
| WKUP_GPIO0_VIRT | Device INTCs must be configured to enable the interrupt request generation. For information about enabling WKUP_GPIO0_VIRT interrupts, see Interrupts. |
| GPIO0_VIRT | Device INTCs must be configured to enable the interrupt request generation. For information about enabling GPIO0_VIRT interrupts, see Interrupts. |
| DMSC_WKUP_0 | Device INTCs must be configured to enable the interrupt request generation. For information about enabling DMSC_WKUP_0 interrupts, see Interrupts. |
| Interconnects | For information about the WKUP_CBASS0, and CBASS0 interconnects configuration, see System Interconnect. |
