NOTES:
1. Not required if using the internal oscillator
option.
2. BKGD/MS is the same pin as PTC6.
3. The 64-pin LQFP combines (V
SSAD
to
V
REFL
) and combines (V
DDAD
to V
REFH
)
4. V
LCD
, V
LL1
, V
LL2
, and V
LL3
can be
powered internally using V
DD
or
externally based on software
configuration of the LCD module.
(Shown as internally powered).
5. V
LCD
is a “no connect” when the LCD
module is being powered via V
DD
.
6. An RC filter on
RESET is recommended
for EMC-sensitive applications.
