Probably would only catch newbies, but since a lot of such use
this chip first, I'll mention them:

1)      The fact RA4 is open-drain only when used as an output is not
         mentioned on Page 11, whereas it is on, say the 16F876.

         16F62x: Bi-directional I/O port/Can be configured as
T0CKI/comparator output

         16F87x: RA4 can also be the clock input to the Timer0 module.
Output is open drain type.

2)      RA6/OSC2/CLKOUT description says:

         Bi-directional I/O port/Oscillator crystal output. Connects to
crystal or resonator in crystal
         oscillator mode. In ER mode, OSC2 pin outputs CLKOUT which has 1/4
the frequency
         of OSC1, and denotes the instruction cycle rate.

         When this is actually optional behavior, so RA6 can be used for
general
         purpose I/O while using ER mode (there are two ER modes, with and
         without clock/4 output on RA6).
