ANY MCU RESET SOURCE ASSERTED
This mode is entered from power off mode whenever the BDLC supply
voltage, V
(V
reset must be asserted while powering up the BDLC or an unknown state
will be entered and correct operation cannot be guaranteed. Reset mode
is also entered from any other mode as soon as one of the MCU’s
possible reset sources (such as LVR, POR, COP watchdog, reset pin,
etc.) is asserted.
In reset mode, the internal BDLC voltage references are operative, V
is supplied to the internal circuits which are held in their reset state, and
the internal BDLC system clock is running. Registers will assume their
reset condition. Because outputs are held in their programmed reset
state, inputs and network activity are ignored.
