// DESCRIPTION:
// Main function. Performs system initialization and loops infinitely.
//
//-----------------------------------------------------------------------------
//
// ARGUMENTS: None

// THEORY of OPERATION or PROCEDURE:
// 1) Start the user modules
// 2) Loop Infinitely

{
mainc() //Enable the Global Interrupt M8C_EnableGInt;
//Enable the Timer interrupt and Start the UM Timer8_1_EnableInt();

// FUNCTION NAME: Timer8_1_ISR_C

// DESCRIPTION:
// Interrupt Service routine of Timer8_1 usermodule written in C.
// The _Timer8_1_ISR subroutine In the Timer8_1INT.asm file,

}
