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.
These two pins also can be optioned as an RTC oscillator (32768Hz). In this
case, the system clock comes from an internal RC oscillator whose fre-
quency has 4 options (3.2MHz, 1.6MHz, 800kHz, 400kHz)
