Reset Button, S4
The reset push-button S4, resets the module and the peripherals on the development board.
A push-button allows manual reset by connecting POR# or optionally RSTIN# to ground.
Power Button, S11
The power button S11, generates a Turn On/Turn Off interrupt to the MC13892 power
management device on the module.
The Turn Off event does not directly power off the module. The module is powered off by the
processor's response to this interrupt. The software can configure a user initiated power
down, or a transition to a low power off mode by pressing this power button.
When in Off mode or in low power mode, the module can be powered via the Turn On event
generated by pressing the Power button.
User Buttons, S3 and S5
Use the user push-buttons to interact with the applications running on the ConnectCore for
i.MX51 module. Use these module signals to implement the push-buttons:
Signal Name
DISPB2_SER_DIO/GPIO3_6/USER_KEY1
GPIO1_1/SD1_WP#/SPI_MISO/USER_KEY2
Button
S3
S5
GPIO Used
GPIO3_8
GPIO1_1
GPIO3_6 is used in User Button S3 and also in the Digital I/O connector for Digital I/O7.
Ident Button, S10
The Ident push-button S10 is associated to the commissioning input of the Digi XBee modules.
This input provides a variety of simple functions to aid in deploying devices in a network. For
a deeply description of this functionality please refer to the Digi XBee modules
documentation.
Legend for Multi-Position Switches
Switches S6, S7, S8 and S9 are multi-pin switches. In the description tables for these
switches, the position is designated as S[switch number].[pin number]. For example, position
1 on switch S6 is specified as S6.1.
