OSC1, OSC2 are connected to an RC network or Crystal
(determined by ROM code option) for the internal system
clock.InthecaseofRCoperation,OSC2istheoutputtermi-
nal 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,thesystemclockcomesfromaninternalRCoscillator
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 disabled. Otherwise the PG1 and
PG2 are used as internal registers (pull-high resistors are
always disabled).
Note: * The pull-high resistors of each I/O port (PA, PB, PC, , PG) are controlled by a ROM code
options.
CMOS or Schmitt trigger option of port A is controlled by a ROM code option.
