These functions are provided by the Platform Support Package (PSP) to perform various tasks. They are designed for a specific microcontroller and development board. You may need to port them to work with your hardware solution; they are designed to make porting easy.
The package includes samples in the psp_isr.c file.
|psp_isr_install()||Initializes the ISR.|
|psp_isr_delete()||Deletes the ISR, releasing the associated resources.|
|psp_isr_enable()||Enables the ISR.|
|psp_isr_disable()||Disables the ISR.|
|psp_int_enable()||Enables global interrupts.|
|psp_int_disable()||Disables global interrupts.|
These functions are described in the following sections.
