While operating with protections enabled, is not possible to manually control PCHG and PDSG. This is done autonomously by the chip. The only possible way to do this is by using TEST_MODE (FET_EN = 0), but this disables all automatic protections in the device so is therefore not recommended for systems in operation. By writing to registers, the PCHG and PDSG can be configured to turn off after a set amount of time or stay on until set voltage is reached while still having protections enabled. For discharge, the registers are Settings:FET:Predischarge Timeout and Settings:FET:Predischarge Stop Delta. For PCHG, the register is Settings:FET:Precharge Stop Voltage.
