Data Structures

Overview

Structs used by the driver.

Note

This is an example show how to instantiate PLIC with plic_instance_t and plic_hwreg_t.

plic_instance_t wdg_plic = {
   .target     = BSP_PLIC_CPU_0,
   .gateway    = WATCHDOG_SOFT_PANIC_INTERRUPT,
   .priority   = 0x1U, 
   .enable     = 0x1U, 
   .threshold  = 0x0U,
};
 
// Apply Config for PLIC & WDG setting
plic_applyConfig(&wdg_plic);
