请问CC3200 HIB通过gpio高电平的时候唤醒板子，退出HIB，应该怎么设置这几个值？

我这边是通过PRCM_HIB_GPIO4唤醒的，gpio4分别连着gpio3/gpio9和gpio22，怎么在唤醒的时候获取到具体是哪个gpio口唤醒的？

参考如下代码

//****************************************************************************
//
//! Enter the HIBernate mode configuring the wakeup timer
//!
//! param none
//!
//! This function
//! 1. Sets up the wakeup RTC timer
//! 2. Enables the RTC
//! 3. Enters into HIBernate
//!
//! return None.

//****************************************************************************
void EnterHIBernate()
[
#define SLOW_CLK_FREQ (32*1024)
//
// Configure the HIB module RTC wake time
//
MAP_PRCMHibernateIntervalSet(5 * SLOW_CLK_FREQ);
//
// Enable the HIB RTC
//
// MAP_PRCMHibernateWakeupSourceEnable(PRCM_HIB_SLOW_CLK_CTR);
//------------------------------------------------------------Hib模式下增加GPIO唤醒---------------------------------------------------------------
// PRCMHibernateWakeupSourceEnable入口参数
// PRCM_HIB_SLOW_CLK_CTR -PRCM_HIB_GPIO2 -PRCM_HIB_GPIO4 -PRCM_HIB_GPIO13 -PRCM_HIB_GPIO17 -PRCM_HIB_GPIO11 -PRCM_HIB_GPIO24 -PRCM_HIB_GPIO26
PRCMHibernateWakeupSourceEnable(PRCM_HIB_GPIO13);
PRCMHibernateWakeUpGPIOSelect(PRCM_HIB_GPIO13,PRCM_HIB_FALL_EDGE); //按键按下去产生上升沿，松开后产生下降沿！注意入口参数的顺序！！！
//------------------------------------------------------------------------------------------------------------------------------------------------
// DBG_PRINT("HIB: Entering HIBernate...nr");
UART_PRINT("Entering HIBnr");
MAP_UtilsDelay(80000);

//
// powering down SPI Flash to save power
//
Utils_SpiFlashDeepPowerDown();
//
// Enter HIBernate mode
//
MAP_PRCMHibernateEnter();
]

// set_rtc_as_wk_src(WK_LPDS, LPDS_DUR_SEC, false); //测试LPDS功耗，不使用定时器唤醒，仅使用GPIO唤醒！
// set_gpio_as_wk_src(WK_LPDS, GPIO_SRC_WKUP, PRCM_LPDS_FALL_EDGE);
//------------------------------------------------------------------注意！！---------------------------------------------------------------------------------------------
// set_gpio_as_wk_src(WK_HIB, GPIO_SRC_WKUP, PRCM_LPDS_FALL_EDGE); //必须设置进入Hib模式下的中断唤醒源，否则无法进入Hib模式
//注意在sl_Stop(10)之前不要启动该语句，否则NWP在sl_Stop(10)之后就自动进入了Hib模式但是唤醒源并没设置OK，直接屏蔽该语句，用EnterHIBernate();即可
// 对应低功耗模式：
// e_pm_S0, // CPU & HW modules are functioning at optimal & intended freq Active模式
// e_pm_S1, // CPU is halted, high freq PLL CLK is available to HW modules Sleep模式
// e_pm_S2, // CPUSS is clk gated, Mid freq CLK is availalbe to HW modules DPS模式
// e_pm_S3, // SoC almost pwr off, slow CLK is present & OCRAM is retained LPDS模式
// e_pm_S4 // SOC almost pwr off, slow CLK is present & few regs retained hib模式
