Not able to configure P4_6 pin as input interrupt on mcxn947

#define CINT_GPIO GPIO4
#define CINT_PORT PORT4
#define CINT_PIN 6U
#define CINT_IRQ GPIO40_IRQn
#define CINT_IRQ_HANDLER GPIO40_IRQHandler

CLOCK_EnableClock(kCLOCK_Gpio4);
CLOCK_EnableClock(kCLOCK_Port4);
GPIO_SetPinInterruptConfig(CINT_GPIO, CINT_PIN, kGPIO_InterruptFallingEdge);
NVIC_EnableIRQ(CINT_IRQ);
gpio_pin_config_t sw1_config =
{
kGPIO_DigitalInput,
0,
};
/* Sets the input pin configuration */
GPIO_PinInit(CINT_GPIO, CINT_PIN, &sw1_config);
PRINTF("Init CINT\r\n");

void CINT_IRQ_HANDLER(void)
{
GPIO_GpioClearInterruptFlags(CINT_GPIO, 1U << CINT_PIN);
g_touch = true;
SDK_ISR_EXIT_BARRIER;
}

Does GPIO00_IRQn maps to port 0 pins 0-15 and GPIO01_IRQn to 16-31?

感谢您的确认。
我在将 P4_6 引脚设置为输入中断时遇到了问题。当我为端口 0 引脚进行配置时，同样的代码工作正常，但对于 P4_6 似乎不起作用。
MCXN947 的所有引脚都能配置为 GPIO 输入中断吗？
如能提供任何帮助，将不胜感激。Re: Not able to configure P4_6 pin as input interrupt on mcxn947

嗨，@sstcor、

没错。每个 GPIO 有两个中断向量；每个端口的 32 个引脚各占一半。
