Note:

The Timer1 oscillator shares the T1OSI and T1OSO pins with the PGD and PGC

pins used for programming and debugging.

When using the Timer1 oscillator, In-Circuit Serial Programming (ICSP) may not

function correctly (high voltage or low voltage), or the In-Circuit Debugger (ICD) may

not communicate with the controller. As a result of using either ICSP or ICD, the

Timer1 crystal may be damaged.

If ICSP or ICD operations are required, the crystal should be disconnected from the

circuit (disconnect either lead) or installed after programming. The oscillator loading

capacitors may remain in-circuit during ICSP or ICD operation.
