Figure 34.5. Two 8-bit Timers in Capture/Capture Configuration (Split Mode)

34.6. 8-Bit Timer/Capture Mode (Split Mode)

When TMR2SPLIT=1, TMR2L_CAP=1 and TMR2H_CAP=0, the split timers operate one in 8-bit timer

mode and the other in 8-bit capture mode. Same situation happens when TMR2L_CAP=0 and

TMR2H_CAP=1, only the roles of the timer 8-bit halves are reversed. The only difference in between these

two scenarios are the interrupt flags settings, since TMR2INTH and TMR2INTL are not symmetrical. The

TMR2INTL has a local enable TMR2INTL_EN. The functionality of the 8-bit timer and 8-bit capture modes

for the respective halves is the same as described above when both halves operate in the same mode.
