CR3 is set red and CR4 is set amber upon receiving an NMT reset command from the OC. If the DSP can successfully reset, all
the LEDs will be turned off and then altered again during normal execution.
Specific CR4 functions: After the DTC becomes operational, unhandled interrupts might occur. These are reflected by a staying
solid red or blinking CR4.
A blinking red CR4 will blink for a count, pause, and then blink repeat the count again (continuously). Count the blinks between
pauses and determine the cause using the following list:
Blinks
Source
1 (unused)
2 (rfu)
3 non-maskable
4 illegal operation
5 data logger
6 RTOS
7 Emulation
8 CPU timer 1
9 CPU timer 2
When a solid re CR4 occurs, the status of CR1 through 3 identify the interrupt source:
CR1 CR2 CR3 CR4
