abi_msp430_interrupt
The tracking issue for this feature is: #38487
In the MSP430 architecture, interrupt handlers have a special calling
convention. You can use the "msp430-interrupt"
ABI to make the compiler apply
the right calling convention to the interrupt handlers you define.
#![feature(abi_msp430_interrupt)]
#![no_std]
// Place the interrupt handler at the appropriate memory address
// (Alternatively, you can use `#[used]` and remove `pub` and `#[no_mangle]`)
#[link_section = "__interrupt_vector_10"]
#[no_mangle]
pub static TIM0_VECTOR: extern "msp430-interrupt" fn() = tim0;
// The interrupt handler
extern "msp430-interrupt" fn tim0() {
// ..
}
