16.8.11 Register C6h PROCHOT Override
Note that if the P1P2_PROCHOT bit is set to short the Px_PROCHOT pins together, both Px_PROCHOT outputs will be driven
together, even if only one of the FORCE_Px bits is set.
The period of the PWM signal driven on Px_PROCHOT is 3.56 ms (80 internal 22.5 kHz clocks). The asserted time can be
increased in 5 clock increments. 5 clocks is about 220 µs and would represent 6.25% percent throttled.

When this is set by software, P1_PROCHOT will be asserted
by the LM93 with the duty cycle selected by PHT_DC.
When this is set by software, P2_PROCHOT will be asserted
by the LM93 with the duty cycle selected by PHT_DC.
