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.
