NOTES:
1. Not required if using the
internal oscillator option.
2. These are the same pins as
PTG1 and PTG2.
3. BKGD/MS is the same pin
as PTG0.
4. The 48-pin QFN has 2 V
SS
pins (V
SS1
and V
SS2
), both
of which must be connected
to GND.
5. RC filters on RESET
and
IRQ are recommended for
EMC-sensitive applications
