not be guaranteed by using these hot-plug signals, it is recommended that the RESET_MOCI#
signal is used as reset.
The clock request output of the card (CLKREQ#, Pin 7) can be left unconnected. It might also be
connected to a free GPIO on the Apalis module. In this case, the clock request functionality needs
to be implemented in software.
The wake output of the Mini PCIe Card (WAKE#, pin 1) can be connected to the general wake
input of the Apalis module (WAKE1_MICO#). Wake-up-capable Mini PCIe Cards such as Wi-Fi
cards can use this signal to wake up the module from its suspend state.
The R-UIM interface of the Mini PCIe Card (UIM, pin 8, 10, 12, 14 and 16) are only needed for
mobile broadband modem cards such as 3G cards. If the card interface needs to support such
modems, an additional SIM card holder needs to be attached to this interface.
The Mini PCIe Card pin-out features an SMB interface for additional power management control.
As the SMB and I2C buses are compatible, it is recommended that the I2C1 interface on the Apalis
module is used if the SMB interface is needed. Most PCIe cards do not make use of the SMB
interface. Therefore, these pins can be left unconnected for most applications.
