Chapter 4 4BSample Code Manual
4.3.3 Vectors.c File
The Vectors.c contains the MB95200 Series MCU Interrupt vector definition.
User can pre-set all interrupt control registers in function InitIrqLevels(). It can be used to set
all interrupt priorities in static applications. For example, to set the external interrupt ch.0 to
level 0, change the following code:
ILR0 = 0xFF;
// IRQ0: external interrupt ch.0 | ch.4
// IRQ1: external interrupt ch.1 | ch.5
// IRQ2: external interrupt ch.2 | ch.6
// IRQ3: external interrupt ch.3 | ch.7
To
ILR0 = 0xFC;
// IRQ0: external interrupt ch.0 | ch.4
// IRQ1: external interrupt ch.1 | ch.5
// IRQ2: external interrupt ch.2 | ch.6
// IRQ3: external interrupt ch.3 | ch.7
And declare the interrupt function as in Vectors.c below,
……
__interrupt void external_int00 (void);
……
#pragma intvect external_int00 0 // IRQ0: external interrupt ch0 | ch4
Then user can write his own interrupt sub-routine in Main.C shown as below.
/*--------------------- INTERRUPT SERVICE ROUTINE -------------------------
--*/
__interrupt void external_int00(void)
{
//User code
}
4.3.4 Main.c File
Main.c contains the user code.
