3.10User LEDs

The IQ80960RM/RN platform has a bank of eight user-programmable LEDs, located on the upper edge of the adapter board. These LEDs are controlled by a write-only register and used as a debugging aid during development. Software can control the state of the user LEDs by writing to the LED Register, located at E004 0000H. Each of the eight bits of this register correspond to one of the user LEDs. Clearing a bit in the LED Register by writing a “0” to it turns the corresponding LED “on”, while setting a bit by writing a “1” to it turns the corresponding LED “off”. Resetting the IQ80960RM/RN platform results in clearing the register and turning all the LEDs “on”. The LED Register bitmap is shown in Figure 3-1.

The user LEDs are numbered in descending order from left to right, with LED7 being on the left when looking at the component side of the adapter.

3.10.1User LEDs During Initialization

MON960 indicates the progress of its hardware initialization on the user LEDs. In the event that initialization should fail for some reason, the number of lit LEDs can be used to determine the cause of the failure. Table 3-10lists the tests that correspond to each lit LED.
