The host microprocessor/microcontroller and the PCF8531 are both connected to the
I
pull-up resistors. The internal oscillator requires no external components. The appropriate
intermediate biasing voltage for the multiplexed LCD waveforms are generated on-chip.
The only other connections required to complete the system are to the power supplies
