Current Profile Time out & Detection Interrupted
If the Current Profile Time out value is achieved before the completion of the test, the current profile test has failed.
If this failure occurred, the Current Profile Time out bit in the SPI message is set.
The Current Profile Time out value is programmable and should be set to a value less than the PWM period.
If the OUTx pin is turned off before the completion of the test as in Figure 18, the Detection Interrupted SPI Bit is
set. Note that the OUTx pin must transition from high to low to set the Detection Interrupted fault bit. The Detection
Interrupted fault bit is not set by the expiration of the PWM period if the duty cycle is set to >= 100%.
If the entire CPD test passes (all three zones are passed before the time out), the "Passed Since Last Read" SPI
bit is set SPI message # 18.
Each channel of the Adler 2 is individually configurable for the current profile detection patterns.
The thresholds and counts for each zone must not be changed via SPI while a current profile detection sequence
is active, otherwise an incorrect detection may occur.
