The F
features.
The Timer1 oscillator crystal driver is powered whenever T1OSCEN (T1CON) or T3OSCEN (T3CON) = 1.
The circuit is enabled by the logical OR of these two bits. When disabled, the inverter and feedback resistor
are disabled to eliminate power drain. The TMR1ON and TMR3ON bits do not have to be enabled to power
up the crystal driver.
RD16: 16-Bit Read/Write Mode Enable bit
1 = Enables register read/write of Timer1 in one 16-bit operation
0 = Enables register read/write of Timer1 in two 8-bit operations
TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1
OSC
clock source should not be selected if the timer will be used with the ECCP capture/compare
