Can someone tell me why the following IF condition (see below) doesn't seem to capture? The else works fine when PORT1, PORT3 or PORT5 is called....
void Timer_PWM(Timer_RegDef_t *pTIMERx, uint8_t WhichCCRegister, uint8_t Output, uint16_t LoadValue, \
GPIO_RegDef_t *pGPIOx, uint8_t Pin)
{
uint16_t *p;
pGPIOx->POUT |= (1 << Pin);
pGPIOx->DIR |= (1 << Pin);
p = (uint16_t *)(&pGPIOx->SEL[0]);
if ((pGPIOx == PORT2) || (pGPIOx == PORT4) || (pGPIOx == PORT6))
*(p+1) |= (1 << Pin);
else
*p = (1 << Pin);
p = (uint16_t *)(&pTIMERx->TB_CTL);
*(p + CCVALUE_OFFSET + WhichCCRegister) = LoadValue;
*(p + CCCNTRL_OFFSET + WhichCCRegister) &= (0x7 << 5);
*(p + CCCNTRL_OFFSET + WhichCCRegister) |= (Output << 5);
}
The PORTs are defined as follows, along with GPIO_RegDef_t if needed....
