Comparator/level detector circuit
In the Dr.63514 in-circuit emulator, the comparator and level detector blocks are implemented using an
ML63514.

_____________________________________________________________________________________________________
This BACKUP switch is completely unrelated to the backup function of the ML63512/514
being evaluated. The ML63512/514 backup function is implemented using only the
BUPCON register in the Dr.63514 in-circuit emulator.
_____________________________________________________________________________________________________________________
Caution
The BACKUP switch must be set to the operating
voltage used. If the switch is set to the wrong position,
the ML63514 used in the Dr.63514 in-circuit emulator
may be destroyed.
