XE24S100 COMMUNICATIONS CONTROLLER (continued)

USER CODE

The Texas Instruments MSP430F148 microcontroller serves as the communications controller in the XE24S100

transceiver modules; however, the communications functions do not fully utilize the capabilities of the

microcontroller. Xecom has created a way for our customers to run their simple remote monitoring application

on the transceiver’s communications controller saving the complexity and cost of incorporating a separate

microcontroller.

Has shown in the software block diagram above, the User Code interfaces to the rest of the XE24S code

through the User Code Support block. The User Code Support block interfaces to the AT command engine

and serial interface and supports other features such as sub routine calls.

To prevent the User Code from interfering with the communications responsibilities of the controller, the

User Code must be written in User Tasks. Each User task is a simple state machine that can quickly

complete its function. A full description of the requirements of the User Tasks can be found in the “XE24S

User Application Programmers Guide.
