Notes
1.
T is one period of the 76.8 kHz clock source. Note that from power-up, the oscillator start-up time can influence the
availability and period of clock strobes. This can affect the RESET HIGH to READY LOW timing.
When the host re-programs an address word with a host-to-decoder packet ID > 7FH, there is an added delay before
the PCD5008 is ready for another packet.
