ANY MCU RESET SOURCE ASSERTED
The BDLC has five main modes of operation which interact with the
power supplies, pins, and the remainder of the MCU as shown in
27-2.
This mode is entered from reset mode whenever the BDLC supply
voltage, V
guarantee operation. The BDLC will be placed in reset mode by low-
voltage reset (LVR) before being powered down. In this mode, the pin
input and output specifications are not guaranteed.
