Transistor 6 Current Sense.
This register reports the realtime current through Q6. The range is 0 A (0x00) to
80.58 mA (0xFF) in .316 mA steps.
DC-DC Converter Period.
This bit sets the PWM period for the dc-dc converter. The range is 3.906 s (0x40) to
15.564 s (0xFF) in 61.035 ns steps.
Si3211/Si3212 = Reserved.
Bit 6 is fixed to one and read-only, so there are two ranges of operation:
3.906 s–7.751 s, used for MOSFET transistor switching.
11.719 s–15.564 s, used for BJT transistor switching.
