可以使用for循环和宏定义来简化代码，如下所示：

#define READ_DRV(i) gpio_input_bit_get(DRIVER##i##_R_GPIO_Port, DRIVER##i##_R_Pin)

for (int i = 1; i <= 12; i++) {
    int drv = READ_DRV(i);
    // 处理drv的值
}

在这个例子中，我们定义了一个宏定义`READ_DRV(i)`，用于根据输入的参数i读取对应的GPIO引脚状态。在for循环中，我们循环遍历12个引脚，依次读取它们的状态并进行处理。

需要注意的是，宏定义中使用了双井号（##）运算符，用于将参数i与固定的字符串DRIVER进行拼接，形成对应的GPIO引脚的名称。这样，我们就可以使用一个宏定义来简化对多个GPIO引脚的读取操作。

nrf_drv_common_irq_enable

`nrf_drv_common_irq_enable`是一个来自 Nordic Semiconductor 的 nRF5 SDK 中的一个函数，主要用于在驱动中启用中断。它通常用于处理通用中断，如GPIO、定时器或其他特定于硬件的中断源。这个函数的作用是将指定的中断请求线连接到系统级中断控制器（通常是NVIC），使其能够接收到中断事件并将其传递给相关的中断处理函数。

该函数的一般调用格式如下：

nrf_status_t nrf_drv_common_irq_enable(uint32_t irq_num);

其中，`irq_num` 参数是中断编号，对应具体的硬件中断请求，例如 `GPIOTE_IRQn` 或 `TIMER0_IRQn` 等。

在使用这个函数之前，通常需要确保中断请求已经被正确配置和初始化，包括但不限于设置中断触发模式、优先级以及配置中断处理函数。当函数返回 `NRF_SUCCESS` 表示成功启用中断，如果失败则会返回错误码。

例如启用某个中断前的配置：

// 初始化中断配置
NRF_APP_ERROR_CHECK(NRF_COMMON_APP_irq_enable(GPIOTE_IRQn)); // 启动GPIO中断

// ...其他中断配置...

// 确保中断服务注册
APP_IRQ_SERVICE_DEFINE(MyCustom_IRQn, ..., MyCustom_IRQHandler, NULL, MY_CUSTOM_IRQn, true);

// 具体中断启用
APP_IRQ_ENABLE(MyCustom_IRQn);
