DESCRIPTION
CPUS2
X2
Select 2 for 2XCPU and CPU frequencies. See Table above.
Crystal connection. Connect to 32.768 kHz crystal. Includes internal
XTAL load capacitance.
Crystal connection. Connect to 32.768 kHz crystal. This pin includes
internal XTAL load capacitance and feedback bias for a 32.768 kHz crystal.
Separate power supply connection for 32.768 kHz clock. Will operate down to
2.0V, independent of the rest of the circuit VDD.
Connect to +3.3V or +5V.
Connect to ground.
24 MHz floppy (or super I/O) clock output.
32.768 kHz square wave clock output.
Keyboard clock output, fixed 16 MHz (-06) or 12 MHz (-07).
Power-down 24M+keyboard. Shuts off both clock outputs, pins 7 & 9 when
low.
14.318 MHz system clock output.
Connect to ground.
Connect to +3.3V or +5V.
CPUCLK output. See Table above.
Select 0 for 2XCPU and CPU frequencies. See Table above.
Select 1 for 2XCPU and CPU frequencies. See Table above.
