Regulator enable input:稳压器使能输入;
Can also be sensed as an input:也可以传感信号输入;
Regulator enable and multifunction button. A high input (tolerant to VBAT) enables the on-chip regulators, which can then be latched on internally and the button used as a multifunction input:稳压器使能和过功能按钮.高输入(可以耐受VBAT)使能偏上稳压器,可内部锁存,此按钮可作为多功能输入。
我有找到一段說明,所應該可行,可以試看看,
PIO24 is reserved for the VREG enable line which is usually used as a power button on the hardware. PIO25 is reserved for the CHARGER enable line which is usually used to detect the presence of the charger on the hardware.
