14.3.2 Auto-Reload Mode, Counting up
The auto-reload mode as an up counter is enabled by clearing the ^{CP / RL2} bit in the T2CON regis-
ter. In this mode, Timer/Counter 2 is a 16 bit up counter. When the counter rolls over from 0FFFFh, a
reload is generated that causes the contents of the RCAP2L and RCAP2H registers to be reloaded
into the TL2 and TH2 registers. The reload action also sets the TF2 bit. If the EXEN2 bit is set, then a
negative transition of T2EX pin will also cause a reload. This action also sets the EXF2 bit in T2CON.
