Ensure that there is no large capacitance on RESET_N pin.
3.11. PON_TRIG
BG950A-GL & BG951A-GL modules provide one PON_TRIG pin which is used to wake up the module
from PSM.
Table 11: Pin Definition of PON_TRIG
PON_TRIG can realize the following functions:
Control the module to enter or exit PSM mode and sleep mode.
Enable/disable the main UART interface communication function.
Used for the turn-on/off application of the module.
PON_TRIG must be designed to allow for external control. A reference circuit is shown in the following
figure.
