When T2SPLIT = ‘1’, the Timer 2 registers (TMR2H and TMR2L) act as two 8-bit counters. Each counter
counts up independently and overflows from 0xFF to 0x00. Each time a capture event is received, the con-
tents of the Timer 2 registers are latched into the Timer 2 Reload registers (TMR2RLH and TMR2RLL). A
Timer 2 interrupt is generated if enabled.
