Analog Ground. For noise reasons, analog and digital grounds should
connect together only at the RSC-164.
External Memory Address Bus
Analog In, low gain. (range AGND to AVDD/2.)
Analog In, hi gain (8X input amplitude of AIN0, same range)
Analog Voltage. For noise reasons, keep this supply independent of
digital circuitry.
Pulse Width Modulator Output0
Analog Output (unbuffered).
External Data Bus
Digital Ground, CPU core (pins 1 and 33) and I/O (pins 18and 52)
Power Down. Active high when powered down.
General Purpose Port I/O. Pin P0.0 can act as an external interrupt
input. All I/O pins can act as “wake up” inputs.
