33.4. 8-bit Timer/Timer Mode (Split Mode)
When TMR2SPLIT=1, the timer operates as two independent 8-bit timers. Each of the 8-bit timers can
independently operate in either 8-bit timer or 8-bit capture modes. The only common signals for both 8-bit
timers are capture event input signal and the interrupt output signal. Therefore, four possible configura-
tions are possible in split mode. All of them are described in the subsequent sections.
If TMR2L_CAP=0 and TMR2H_CAP=0, both halves operate as two independent 8-bit timers with indepen-
dently set clocks.
As the 8-bit timer register increments and overflows from 0xFF to 0x00, the 8-bit value in the time reload
registers (TMR2RH or TMR2RL) is loaded into the corresponding timer register (TMR2H or TMR2L), and
the corresponding byte overflow flag TMR2INTH or TMR2INTL are set, respectively. If timer interrupts are
enabled (see IE and EIE1 registers), an interrupt will be generated on each timer overflow.
