it is correct.
if you use FF877, it works only up to 4MHz with a supply between 2 to 3V.
from above 3V to 5V , it reaches 10MHz and that is the Maximum.
the F877A starts working at 4V onwards to 5V but can work at 20MHz

Mmmm. How is example c) correct then ? The example c) on page 231 refers to the 'F877A, not the LF version.
From the device marking PIC16F877A-I/P, they (Microchip) have somehow determined that this is a 10Mhz part.
The example given does not match device spec information elsewhere in the data sheet.
thecritic - Rest assured 16f877A-i/p runs at 20Mhz. I have used it at that. Sorry if this wan't your worry.
Appreciate your reply - not so much 'worry', but the device data sheet is now 7 years old, and you'd have thought that any typo's (assumption) would have been corrected by now ...
