Cautions
⚫
EN outputting low level takes priority. When any low-level output condition is met, EN outputs low level. When all
low-level conditions are not met, EN outputs high level.
⚫
When the EN output in at low level, it means that the module is busy, and the working mode detection will not be
carried out at this time. When the module EN output is at high level, it means the mode switching will be completed
within 1 ms.
⚫
After switching to the new working mode, the module will enter the mode at least 2 ms after the rising edge of EN.
When the EN output is always at high level, the mode switching will take effect immediately.
⚫
When entering from sleep mode to other modes or during reset, the module will reset the parameters, during which
EN output is low.
