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).

Positive power supply

OSC1 and OSC2 are connected to an RC network or a crystal (by options)

O

I

for the internal system clock. In the case of RC operation, OSC2 is the output

Crystal or RC 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.
