The 32-Bit Timer Configuration bit, T32, must be set for 32-bit timer/counter operation. All control bits are
respective to the T2CON and T4CON registers.
The Timer clock input must be assigned to an available RPn pin before use. Please see Section 10.4 âPeripheral
Pin Selectâ for more information.
The ADC event trigger is available only on Timer2/3 in 32-bit mode and Timer3 in 16-bit mode.
