3
Supply
Ground
4
Input
Serial wire clock (SWD Interface). Uses in-
ternal pull down resistor. Do not connect if
not needed.
5
Input
Serial wire input/output (SWD Interface).
Uses internal pull up resistor. Do not con-
nect if not needed.
6
P0.18
Input
Reset pin. A low signal resets the module.
Uses internal pull up resistor
1
.
7
P0.02
2
Input
Boot pin. A low signal during and shortly af-
ter reset starts the module in firmware up-
date bootloader mode. Uses internal pull
up resistor.

. This pin is checked during start-
up to determine the mode of operation.
LOW level or open:
Command Mode.
HIGH level: Transparent Mode. Do not con-
nect if not needed.
