PRODUCTION DATA
The normal sequence summary is as follows:
See Table 10-9 for an example of the first loop sequence.
Step | Register | Data | Description |
---|---|---|---|
1 | WD_INPUT_TRIG (0x15) | [W] 0xFF | Start the watchdog (since it isn’t started yet), also keep a timer internally to flag when response window 1 ends and window 2 starts. |
2 | WD_QA_QUESTION (0x2F) | [R] 0x3C | Read the question. Question is 0x3C |
3 | WD_QA_ANSWER (0x2E) | [W] 0x58 | Write answer 3 (See Table 10-5 example answers to questions with default settings to see answers) |
4 | WD_QA_ANSWER (0x2E) | [W] 0xA8 | Write answer 2 |
5 | WD_QA_ANSWER (0x2E) | [W] 0x57 | Write answer 1 |
6 | WD_QA_ANSWER (0x2E) | [W] 0xA7 | Write answer 0 once window 2 has started |
At this point, you can read the WD_QA_QUESTION (0x2F) register to see if the error counter has increased or if QA ERROR is set.
