C Specification

void SVC_Halt( void ); 

Arguments

None.

Return Values

None.

Description

This function stops the CPU core and goes into a halt state.

This function restores to the interrupt request (set to IF) when the corresponding interrupt request (set to IE)is allowed. This function restores from a halt when the CPSR IRQ disable flag has been set, but no interrupt is generated. This is the state that results when OS_DisableInterrupts() is called.

Restoration will not be possible if the program enters a halt state after the IME has been cleared. This is the state that results when OS_DisableIrq() is called.
