The BDLC has five main modes of operation which interact with the
power supplies, pins, and rest of the MCU as shown in
For the BDLC to guarantee operation, this mode is entered from reset
mode whenever the BDLC supply voltage, V
minimum specified value. The BDLC will be placed in reset mode by
low-voltage reset (LVR) before being powered down. In power off mode,
the pin input and output specifications are not guaranteed.
