RAM Page Select. These signals support selection of one out of four RAM
pages. Each page is 64kbytes in size.
MSM6679AL-110 Reset. External logic should assert this power-on reset
signal LOW when power is applied to the MSM6679AL-110.

Ground.
Oscillator 0/External Clock. When the MSM6679AL-110 uses a crystal
oscillator, this input is the oscillator input pin. The pin is then connected to
one side of a crystal and load capacitor. When used with an external clock,
the external clock is applied to this input.
Oscillator 1. When the MSM6679AL-110 uses a crystal oscillator, this output
is the oscillator output pin. The pin is then connected to one side of a crystal
and load capacitor. When used with an external clock, this output is left
unconnected.
Sleep. When power down mode, this pin becomes low. Sleep signal can be
used for external memory control.
