BQ25895的PDF关于OTG的启动条件：
1. BAT above BATLOWV
2. VBUS less than BAT+VSLEEP (in sleep mode)
3. Boost mode operation is enabled (OTG pin HIGH and OTG_CONFIG bit =1)
4. Voltage at TS (thermistor) pin is within range configured by Boost Mode Temperature Monitor as configured
by BHOT and BCOLD bits
5. After 30 ms delay from boost mode enable
现在我的系统能在电池供电的情况下正常启动OTG, 能不能通过OTG引脚或OTG_CONFIG bit 主动关闭 OTG呢？ 我自己测试修改OTG_CONFIG bit（REG03=0x1A），但是PIDM还是有正常电压输出.。OTG不能主动关闭吗？
