Step Action
3 Repeat step 2 for each season, until all season configurations have been read.
This means step 2 shall be performed the same number of times as the value
read in step 1.
Note – Step 1 initiates the readout procedure and can NOT be left out, even if
the number of seasons used is already known.
Note – The Season number register can optionally be read together with the
Season registers in step 2. The Season number register holds the current season
number, starting from 1 after reading the Number of seasons register. It is
incremented every time the Season registers are read.
