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 8-2 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).
