Module interrupt 

Minimal interrupt helpers mirroring embassy-imxrt style for OS_EVENT and LPUART2. Type-level interrupt traits and bindings are provided by the embassy_hal_internal::interrupt_mod! macro via the generated module below.

Functions

DefaultHandler^⚠

Provide a conservative default IRQ handler that avoids wedging the system. It clears all NVIC pending bits and returns, so spurious or reserved IRQs don’t trap the core in an infinite WFI loop during bring-up.

clear_default_handler_snapshot

default_handler_snapshot

install_irq_handler^⚠

Install an interrupt handler into the current VTOR-based vector table. This writes the function pointer at index 16 + irq number. Safety: Caller must ensure VTOR points at a writable RAM table and that handler has the correct ABI and lifetime.

os_event_install_handler_raw^⚠

Install OS_EVENT handler by raw address. Useful to avoid fn pointer type mismatches. Safety: Caller must ensure the address is a valid extern "C" fn() handler.

vtor_set_ram_vector_base^⚠

Set VTOR (Vector Table Offset) to a RAM-based vector table. Pass a pointer to the first word in the RAM table (stack pointer slot 0). Safety: Caller must ensure the RAM table is valid and aligned as required by the core.
