When T3SPLIT = ‘1’, the Timer 3 registers (TMR3H and TMR3L) 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 3 registers are latched into the Timer 3 Reload registers (TMR3RLH and TMR3RLL). A
Timer 3 interrupt is generated if enabled.
