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