3-3. System Limitations

3-3-1. Resources Uses

The user connectors (CN1 and CN2) on the JOB60851 board make available to the user application

system almost all onboard MSM66Q573 microcontroller pins and thus most microcontroller

functionality.

The JOB60851 board, however, monopolizes certain microcontroller resources in running its own

system, making them unavailable to the developer.

Tables 3.3.1 through 3.3.3 list the MSM66Q573 pin assignments.
