The normal sequence summary is as follows:
See Table 10-16 for an example of the first loop sequence.
|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 10-12 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.
