kHz

Internal Operating Frequency

Assumes use of 32.768-kHz Crystal Only

fOP = fOSC ÷ 2 if PLL is NOT Driving Internal Bus

fOP = 32.768 kHz x N, where N = 16, 32, or 64 (Selectable)

and PLL is Driving Internal Bus

NOTES:

1. VDD = 3.0 to 5.5 Vdc ± 10%, VSS = 0 Vdc, TA = 0 °C to +70 °C, unless otherwise noted

2. The minimum period, tILIL, should not be less than the number of cycle times it takes to execute the interrupt service

routine plus 2T tCYC.
