 For ME909s, when the GPIO interface is used for input, the module will not respond in
sleep mode (it will resume response after being waken up from sleep mode by the
WAKEUP_IN pin) and the module is configured to pull-down inside. In sleep mode, the pull-
down resistance is 5–15 K. For the peripheral circuits, see Figure 2-13 .
For ME909s, when the GPIO interface is used for output and the module is not in sleep

mode, the drive current is 4 mA. When the module is in sleep mode, the drive current is
smaller than 0.1 mA. The resistance is maintained at 5–15 K, as shown in Figure 2-14 .
The output level may be changed if there is a stronger pull-up or pull-down. For the
peripheral circuits, see Figure 2-15 .
