At least 1 ms must pass after PWRGOOD rises above VIH25,min from Table 12 and BCLK meets its AC timing
specification until RESET# may be deasserted.

NOTES:
1.
All AC timings for APIC signals are referenced to the PICCLK rising edge at 1.25V. All CMOS signals are referenced at
0.75V.
2.
The minimum frequency is 2 MHz when PICD0 is at 1.5V at reset. If PICD0 is strapped to VSS at reset then the minimum
frequency is 0 MHz.
3.
Referenced to PICCLK Rising Edge.
4.
For Open-drain signals, Valid Delay is synonymous with Float Delay.
5.
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.
