NOTES:
1. RESET pin can only
be used to reset into
user mode, you can
not enter BDM using
RESET pin. BDM
can be entered by
holding MS low
during POR or
writing a 1 to BDFR
in SBDFR with MS
low after issuing
BDM command.
2. RESET/IRQ features
have optional
internal pullup
device.
3. RC filter on
RESET/IRQ pin
recommended for
noisy environments.
4. C , C , R , and R
1 2 F S
are not required
when low range low
power oscillator is
selected.
