Reserved. This pin is reserved for future use and should be left open.
Analog Input. These ten inputs are tied together and serve as the
analog input. Signal conditioning, via a bandpass filter and gain circuit,
is required before this input.
Analog Ground. This pin provides an analog ground point, allowing
independent grounding of the analog and digital circuitry. Separate
grounds reduce the impact of digital switching noise on analog
sampling accuracy.
Analog Reference Voltage. The MSM6679A-110's on-chip A/D
converter uses this analog reference voltage when converting an
analog signal into digital samples
Reserved. These pins are reserved for future use and must be tied to
VDD.
Serial Port Receive. This is the receive data line for serial port.
Serial Port Transmit. This is the transmit data line for serial port.
Reserved. This pin is reserved for future use and should be left open.
Ground.
Oscillator 0/External Clock. When the MSM6679A-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.
Reserved. This pin is reserved for future use and should be left open.
Oscillator 1. When the MSM6679A-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.
Memory Address Latch Enable. An external memory latch is controlled
by this signal, the address latch enable output.
