When the D+/D– detection has finished, some cases require the D+ pin to force a
voltage of 0.6V. This bit allows the system to clear the voltage prior to any
communication on the D+/D– pins. A ‘1’ clears the voltage at the D+ pin if present.
Forces battery detection and provides status of the battery presence. A logic ‘1’
enables this function.
Puts the device in production test mode (PTM) where the input current limit is
disabled. Note that a battery must not be present prior to using this function.
Otherwise the function will not be allowed to execute. A logic ‘1’ enables the PTM
function
