(FAST DECAY MODE)
Mixed decay timing means the time for switching Slow mode to Fast mode in MIXED DECAY MODE.
In Mixed Decay mode, the Fast mode time at the end of chopping Cycle (Tchop) is fixed by data.
The IC is switched from Slow to Fast mode according to the percentage representing mode time in the table
above.
(For example, 12.5% means that 12.5% of the time is in Fast mode and the rest of the time, 87.5%, in
Charge and Slow modes.)
Only when the value is maximum (100%), the mode is Fast Decay mode.
