An 8 Ohm loudspeaker is connected between SPEAKER and GND. Only one loudspeaker
should be connected to this pin. Usually only the CPU drives this pin, however other modules
can also use this signal to drive the system loudspeaker.
KDATA (keyboard data)
bi-directional I/O pin on CPU modules
Keyboard data signal.
KCLK (keyboard clock)
bi-directional I/O pin on CPU modules
Keyboard clock signal.
VBAT (system battery connection)
This pin connects a system battery to all modules.
The battery voltage has to be higher than 3.0V and lower than 4.0V. Either a 3V or 3.6V
battery is recommended.
Note, that there is no battery needed to hold the CMOS-setup data. Your configuration
concerning hard disks, floppy drives etc. is automatically saved in an onboard FRAM.
Nevertheless the battery is necessary to serve the CMOS date and time while power
consumption is turned off.
