IDLE clocks are inserted between the adjacent channels for a total of three IDLE clocks. When channels are
skipped, one more IDLE clock is inserted for each unselected channel. Therefore, there are 3 (inter-channel
IDLE) + 2 (skipped channels) = 5 IDLE clocks between the fundamental and HAE_H3_INDX transfers.
Results Memory
The results memory is organized by the fundamental and 12 harmonic indexes. Each of the 13 potentially analyzed
frequencies has eight locations dedicated to store various power quality measurements. Each frequency is offset from
the next by eight locations.
The HAE Results Memory figure shows the results memory contents.

HAE Results Upper Byte ID
The HAE results are stored in a 24-bit wide memory as shown in
When the system bus moves the results into memory, the HAE hardware appends a unique CHANNEL:INDEX
identifier to the upper byte of each results location. The intent of the ID byte is to help in data parsing of HAE
results.
The 32-bit appended result is as follows:
