Using XINT1

To get one current sensor to work, I will start by using XINT1.

First task is to understand interrupt control - see figure in previous post.

XINT1CR looks like a register.

Here is something useful from google:

If i enable the external interrupt, the interrupt-flag in the
XINT1CR - Register is set but the pogramm doesn´t jump to my defined
subroutine.

I set the XINT1CR = 0x8003;

//0x0001 enable
//0x0002 low priority ( vector address 0Ch ) int6
//0x0004 polarity ( interrupt on falling edge )
//0x8000 clear int flag by writing a 1


I found some useful stuff in Jess's files (MotorcontrolSCI.c) but I do not think that she used this in the final program. I think that she was going to use this for the ADC callibration routine.

EnableInterrupts();

// XIntruptRegs.XINT1CR.all = 0x0005; //allow External interrupt XINT1
// interrupt generated by low-high transition
