System modules

1. To enter BDM mode following a POR, BKGD/MS should be held low during the power-up and for a hold time of tMSH after

VDD rises above VLVD.

1. Typical values assume VREGIN = 5.0 V, Temp = 25 °C unless otherwise stated.

2. Operating in pass-through mode: regulator output voltage equal to the input voltage minus a drop proportional to ILoad.
