本回继续解析inv_enable_sensor_internal函数后续内容。为了便于理解和回顾，再次贴出inv_enable_sensor_internal函数源码，在EMD-Core\sources\Invn\Devices\Drivers\ICM20948\Icm20948DataBaseControl.c中，如下：

static int inv_enable_sensor_internal(struct inv_icm20948 * s, unsigned char androidSensor, unsigned char enable, char * mems_put_to_sleep)
{int result = 0;unsigned short inv_event_control = 0;unsigned short data_rdy_status = 0;unsigned long steps=0;const short inv_androidSensor_to_control_bits[ANDROID_SENSOR_NUM_MAX]={// Unsupported Sensors are -1-1,
