器件型号：MSP430FR2355 是否有人能告诉我、如果情况(见下文)似乎无法满足以下条件、为什么会出现这种情况？ 当 PORT1、PORT3或 PORT5被称为....时，其它器件工作正常
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);
}
端口定义如下、如果需要的话、与 GPIO_RegDef_t 一起....
