NOTES:
1.
VDD = 3.3 Vdc ±10%, VSS = 0 Vdc, TA = –40 °C to +125 °C, unless otherwise noted
2.
Use only AT-cut crystals.
3.
The 2-bit timer prescaler is the limiting factor in determining timer resolution.
4.
The minimum period, tILIL or tIHIH, should not be less than the number of cycles it takes to execute the interrupt service
routine plus 19 tcyc.
