Hi Niklaus,
Please find the content of header file(2410IIC.h):
void __irq IicInt(void);
Definition of corresponding irq in
2410IIC.c(filename)is as follows:
void __irq IicInt(void)
{
U32 iicSt,i;
rSRCPND = BIT_IIC; //Clear pending bit
rINTPND = BIT_IIC;
iicSt = rIICSTAT;
if(iicSt & 0x8){} //When bus arbitration
is failed.
if(iicSt & 0x4){} //When a slave address
is matched with IICADD
if(iicSt & 0x2){} //When a slave address
is 0000000b
if(iicSt & 0x1){} //When ACK isn't
received
switch(_iicMode)
{
case POLLACK:
_iicStatus = iicSt;
break;
case RDDATA:
if((_iicDataCount--)==0)
{
_iicData[_iicPt++] = rIICDS;
rIICSTAT = 0x90; //Stop
MasRx condition
rIICCON = 0xaf;
//Resumes IIC operation.
Delay(1); //Wait
until stop condtion is in effect.
//Too
long time...
//The
pending bit will not be set after issuing stop
condition.
break;
}
_iicData[_iicPt++] = rIICDS; //The
last data has to be read with no ack.
if((_iicDataCount)==0)
rIICCON = 0x2f;
//Resumes IIC operation with NOACK.
else
rIICCON = 0xaf;
//Resumes IIC operation with ACK
break;
case WRDATA:
if((_iicDataCount--)==0)
{
rIICSTAT = 0xd0; //Stop
MasTx condition
rIICCON = 0xaf;
//Resumes IIC operation.
Delay(1); //Wait
until stop condtion is in effect.
//The pending bit will not be
set after issuing stop condition.
break;
}
rIICDS = _iicData[_iicPt++];
//_iicData[0] has dummy.
for(i=0;i<10;i++); //for
setup time until rising edge of IICSCL
rIICCON = 0xaf;
//resumes IIC operation.
break;
case SETRDADDR:
// Uart_Printf("[ S%d ]",_iicDataCount);
if((_iicDataCount--)==0)
break; //IIC
operation is stopped because of IICCON[4]
rIICDS = _iicData[_iicPt++];
for(i=0;i<10;i++); //For
setup time until rising edge of IICSCL
rIICCON = 0xaf;
//Resumes IIC operation.
break;
default:
break;
}
}
