Enabling Global Interrupts

Last Updated: March 20, 2011

How Do I Enable Global Interrupts?


The file contained in the library header directory of each project contains several useful macros. After including "" in your program, you may use macros like M8C_EnableGInt to enable global interrupts. This sets the Global Interrupt Enable (GIE) bit in the CPU Flag register.

Note: The pending interrupts are only recognized if the GIE is set.
