Yup, it sure does say that! Two possibilities come to mind:

1) The simulator assumes that CCP1 doesn't set GO/DONE, only CCP2 does,=20
but the actual chip will work fine.

2) The data sheet is a cut and paste job, and does not reflect what is=20
in the chip. This is not unheard of. According to the block diagram of=20
the Timer1 module for the 16F88X, setting T1ACS to 1 causes Timer1 to=20
count at Fosc instead of Fosc/4, but it doesn't HAVE a T1ACS. They cut=20
and pasted the Timer! block diagram from some other PIC.

The only way to know which is true is to try the actual chip.
