5.2.2.5 Other Functions
Signal Name Pin No I/O Comments
RESET 13 I Active high. The RESET line has a fixed 10kOhm pull down
resistor to ground, followed by a 10kOhm resistor feeding
the base of a transistor.
3VOUT 27 O Used to monitor the state of the regulated supply within the
module. THIS PIN MUST NOT BE USED TO POWER AN
EXTERNAL CIRCUIT.
