ST Buffer is high-speed type when using T3CKI.
Timer3 registers increment on rising edge.
Synchronization does not operate while in Sleep.
The output of SOSC is determined by the SOSCSEL<1:0> Configuration bits.

The operating mode is determined by the clock select
bits, TMRxCSx (TxCON<7:6>). When the TMRxCSx bits
are cleared (= 00), Timer3/5/7 increments on every inter-
nal instruction cycle (F

when it is ‘10’, Timer3/5/7 works as a counter from the
external clock from the TxCKI pin (on the rising edge after
the first falling edge) or the SOSC oscillator.
