8:Configurable Pin Manager

The Configurable Pin Manager is responsible for assignment and control of the configurable pins (CPs) available on the XPort Pro Lx6 embedded device service. There are three configurable pins on the XPort Pro Lx6.

You must configure the CPs by making them part of a group. A CP Group may consist of one or more CPs. This increases flexibility when incorporating the XPort Pro Lx6 into another system.

Note: The blue text in the XML command strings of this chapter are to be replaced with a user-specified name.

CPM: Configurable Pins

Each CP is associated with an external hardware pin. CPs can trigger an outside event, like sending an email message or starting Command Mode on a serial Line.

The Current Configuration table shows the current settings for each CP.

Table 8-1 Current Configurable Pins

CP	Ref	Configured as	Value	Groups	Active in group
CP1	Pin 14	Input	1	2	<available>
CP2	Pin 16	Input	1	0	<available>
CP3	Pin 18	Input	0	2	<available>

	Table 8-2 CP Status
CPM – CPs Status	Description
Name	Shows the CP number.
State	Shows the current enable state of the CP.
Type	Shows the CP hardware pin type. Can be updated. Choices are:
	 Input
	 Output
	When a CP is configured as output, it can be toggled by setting the value.
	Whatever value is given, the first bit 0 is used as the setting. 1 means asserted
	and 0 means de-asserted. Additionally, the CP logic can be inverted so that
	assertion is low.
Value	Shows the last bit in the CP current value.
Bit	Visual display of the bitwise 32 bit placeholders for a CP.
Level	A “+” symbol indicates the CP is asserted (the voltage is high). A “-“indicates the
	CP voltage is low.
I/O	Indicates the current status of the pin:
	 I = input
	 O = output
	 <blank> = unassigned
Logic	An “I” indicates the CP is inverted (active low).
