care”. When T2CS is clear, the timer increments from the internal clock (Fosc/4). When T2CS is set, the timer
increments on every falling edge of the IOB0/T23CKI pin.
For the 16-bit timer to increment, both T2ON and T3ON bits must be set.

Timers in 8-bit mode
When T2CS is set, the 16-bit TMR3:TMR2 increments on the falling edge of clock input T23CKI. The T23CKI input
is synchronized with internal phase clocks. This cause a delay from the time a falling edge appears on T23CKI to the
time TMR3:TMR2 is actually incremented.
