@CHIP-RTOS C Library V2.06 - Hardware API


hal_give_eoi

Give EOI to interrupt controller.

void hal_give_eoi ( unsigned char intr_no );

Parameters

intr_no

Type (0=INT0 ... 4=INT4)

Return Value

-- none --.

Comments

Give End-Of-Interrupt for INT0-INT4.

When installing a interrupt service routine through HW API, it's not neccessay to call this function, because the HW API does it for you.

This function is provided for writing own interrupt service routines without the HAL hal_install_isr function.   Especially when using cascaded mode of the interrupt controller with INT0/INTA, this function is needed for generating an EOI for INT0.
