HIGH_TIME

Programmable Load High Current Period. When the programmable load goes into the high

state, it pulls down the high current for the HIGH_TIME period, which is in units of 10 µs. The

minimum HIGH_TIME is 10 µs. If 0 is written, HIGH_TIME = 1.

COOLDOWN_DECR

Cool Down Decrement. When the pulse current is turned off, the FET power accumulator

is decremented by the COOLDOWN_DECR value every COOLDOWN_TIMESTEP.

MAX_EGY_THR

Maximum Energy Threshold. When the MAX_EGY_THR is exceeded, the device enters cool

down mode. The threshold is scaled by 128. The energy meter accumulates the overscaled

ADC values every 10 µs when the device is not in cool down mode.
