OSC1, OSC2 are connected to an RC network or Crystal (determined by
option) for the internal system clock. In the case of RC operation, OSC2 is
the output terminal for 1/4 system clock. These two pins can also be
optioned as an RTC oscillator (32768Hz) or I/O lines. In these two cases,
the system clock comes from an internal RC oscillator whose frequency
has 4 options (3.2MHz, 1.6MHz, 800kHz, 400kHz). If the I/O option is se-
lected, the pull-high option can also be enabled or disabled. Otherwise the
PG1 and PG2 are used as internal registers (pull-high resistors are always
disabled).
