RTC or
System Clock
Real time clock oscillators. OSC3 and OSC4 are connected to a 32768Hz
crystal oscillator for timing purposes or to a system clock source (depending
on the options).
VDD
Positive power supply
OSC2
OSC1
O
I
Crystal or RC
OSC1 and OSC2 are connected to an RC network or a crystal (by options)
for the internal system clock. In the case of RC operation, OSC2 is the output
terminal for 1/4 system clock.
The system clock may come from the RTC oscillator. If the system clock co-
mes from RTCOSC, these two pins can be floating.
