OSC1, OSC2 are connected to an RC network or Crystal (deter-
mined by ROM code option) for the internal system clock. In the
case of RC operation, OSC2 is the output terminal for 1/4 sys-
tem clock. These two pins can also be optioned as an RTC oscil-
lator (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 selected, the pull-high options can also be enabled or dis-
abled. Otherwise the PG1 and PG2 are used as internal regis-
ters (pull-high resistors are always disabled).
Note: * The pull-high resistors of each I/O port (PA, PB, PC, PG) are controlled by 1-bit ROM code
option.
CMOS or schmitt trigger option of port A is controlled by 1-bit ROM code option.
