NOTES:
1.
All AC timings for APIC signals are referenced to the PICCLK rising edge at 1.0V. All CMOS signals are
referenced at 1.0V.
2.
The minimum frequency is 2 MHz when PICD0 is at 1.5V at reset Referenced to PICCLK Rising Edge.
3.
For Open-drain signals, Valid Delay is synonymous with Float Delay.
4.
Valid delay timings for these signals are specified into 150
to 1.5V and 0 pF of external load. For real system
timings these specifications must be derated for external capacitance at 105 ps/pF.
