REGISTER 12: LCH_STATUS (LATCH-OFF STATUS READBACK), ADDRESS 0x0C

Register 12 contains latched fault flags for thermal shutdown and channel latch-off caused by an OVP or SCP condition. Latched flags are not

reset when the fault disappears but are cleared only when a 1 is written to the appropriate bit (provided that the fault no longer persists).
