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. |
