Nov 30, 2011
Table 6-3 below details the different configurations and functions of the MCU operating mode jumpers.
Reference Position One Position Two Position Three Related Ref.
J1* Pins 1 and 2 shorted.
Connects EMLE to
Board_VCC (bypassed to
GROUND via R324).
Pins 2 and 3 shorted.
Connects EMLE to
GROUND (bypassed by
R324).
All pins open. EMLE is left
to float – DO NOT SET.
R324
Table 6-3: MCU Operating Mode Jumpers
*By default, this jumper is not fitted to the RSK+. R324 is fitted by default, therefore EMLE is connected to
GROUND.
