The output of the on-chip Xtal oscillator
inverter.
The input to the oscillator inverter from the
Xtal circuit or external clock source.
The ‘C-BUS’ serial clock input from the host
The ‘C-BUS’ serial data input from the host
A 3-state ‘C-BUS’ serial data output to the
host C. This output is high impedance when
not sending data to the host C.
The ‘C-BUS’ transfer control input provided by
the host C.
A ‘wire-ORable’ output for connection to a host
pulled down to V SS when active and is high
impedance when inactive. An external pullup
resistor is required.
The negative supply rail (ground).
The sinewave output of the Tones and FSK
signal generators.
The sinewave output of the SPM signal
generator.
