12.2.2
This mode is selected by setting CA1/PR3. A block dia-
gram is shown in Figure 12-8. In this mode, TMR3 runs
without a period register and increments from 0000h to
FFFFh and rolls over to 0000h. The TMR3 interrupt
Flag (TMR3IF) is set on this roll over. The TMR3IF bit
must be cleared in software.
Registers PR3H/CA1H and PR3L/CA1L make a 16-bit
capture register (Capture1). It captures events on pin
RB0/CAP1. Capture mode is configured by the
CA1ED1 and CA1ED0 bits. Capture1 Interrupt Flag bit
(CA1IF) is set on the capture event. The corresponding
interrupt mask bit is CA1IE. The Capture1 Overflow
Status bit is CA1OVF.

The Capture2 overflow status flag bit is double buff-
ered. The master bit is set if one captured word is
already residing in the Capture2 register and another
“event” has occurred on the RB1/CA2 pin. The new
event will not transfer the TMR3 value to the capture
register which protects the previous unread capture
value. When the user reads both the high and the low
bytes (in any order) of the Capture2 register, the master
overflow bit is transferred to the slave overflow bit
(CA2OVF) and then the master bit is reset. The user
can then read TCON2 to determine the value of
CA2OVF.
The operation of the Capture1 feature is identical to
Capture2 (as described in Section 12.2.1).
