Hi,
We want to set a interruption configuration to a lib, access by address.
Detailed code as attached.
typedef interrupt void(*PINT)(void);
#define ADCINT1_OFT 64 // ADC - if Group 10 ADCINT1 is enabled, this must be Rsvd1_1
#define PIEIER1_OFT 0 // PIE INT1 IER register
#define PIEIER_INTx1 (1 << 0 )
#define M_INT1 0x0001
#define PIEACK_GROUP1 0x0001
static const PieCfg AdcIntCfgTab =
{
ADCINT1_OFT,
PIEIER1_OFT,
PIEIER_INTx1,
M_INT1,
PIEACK_GROUP1
};
/**********************************************************************************
***********************************************************************************/
void HwPieInit(void (*UserInterrupt)(void),PieCfg PieTable)
{
PINT UserCfgInt =&PieVectTable.PIE1_RESERVED;
volatile union PIEIER_REG *const PieIerX=&PieCtrlRegs.PIEIER1; // PIE INT1 IER register
EALLOW;
*((volatile Uint16 *)(UserCfgInt+PieTable.PieIntOft))=UserInterrupt;
*((volatile Uint16 *)(PieIerX+PieTable.PieIerXOft))|=PieTable.PieInx;
IER |= PieTable.PieMint;
PieCtrlRegs.PIEACK.all =PieTable.PieAck;
EDIS;
}
#pragma CODE_SECTION(Seq1InterruptServiceRoutine, "ramfuncs");
interrupt void Seq1InterruptServiceRoutine(void)
{
}
void main(void)
{
HwPieInit(&Seq1InterruptServiceRoutine,AdcIntCfgTab);
}
During the position when execute *（（volatile Uint16 *）（UserCfgInt + PieTable.PieIntOft））= UserInterrupt;
In memory browser, the address is 0x003F82D2.
But actually address is 0x0082D2.
1. CCS7.3, the above code can be compiled, but an error occurs when access to the address 0x3F82D2, the jumping to interruption is incorrectly.
2. CCS5.5, failed to compile.
So we change uint16 * to uint32, it's correct.
Q: During the interruption address access, should it be addressed as 16-bit or 32-bit? Thanks a lot.
