Timer1 Oscillator
A crystal oscillator circuit is built in between pins T1OSI (input) and T1OSO (amplifier output). It
is enabled by setting the T1OSCEN control bit (T1CON<3>). The oscillator is a low power
oscillator, rated up to 200 kHz operation. It will continue to run during SLEEP. It is primarily
intended for a 32 kHz crystal, which is an ideal frequency for real-time keeping.
the capacitor selection for the Timer1 oscillator.
The Timer1 oscillator is identical to the LP oscillator. The user must provide a software time delay
to ensure proper oscillator start-up.

Note 1: Higher capacitance increases the stability of oscillator but also increases the start-up

This allows the counter to operate (increment) when the device is in sleep mode,
which allows Timer1 to be used as a real-time clock.
