13.2.3
The Capture overflow status flag bits are double
buffered. The master bit is set if one captured word is
already residing in the Capture register and another
“event” has occurred on the CAPx pin. The new event
will not transfer the TMR3 value to the capture register,
protecting the previous unread capture value. When
the user reads both the high and the low bytes (in any
order) of the Capture register, the master overflow bit is
transferred to the slave overflow bit (CAxOVF) and
then the master bit is reset. The user can then read
TCONx to determine the value of CAxOVF.

READING THE CAPTURE REGISTERS
x = unknown, u = unchanged, - = unimplemented read as '0', q - value depends on condition,
shaded cells are not used by Capture.
Other (non power-up) resets include: external reset through MCLR and WDT Timer Reset.

An example of an instruction sequence to read capture
registers and capture overflow flag bits is shown in
Example 13-1. Depending on the capture source, dif-
ferent registers will need to be read.
