Bit 7: First Edge Hold
Bit [6:4]: Prescale Bit [2:0]
Bit [3:0]: Capture A/B, Rising/Falling Interrupt Enable
Document #: 38-08022 Rev. *D
1 = The time of the first occurrence of an edge is held in the
Capture Timer Data Register until the data is read. Subse-
quent edges are ignored until the Capture Timer Data Regis-
ter is read.
0 = The time of the most recent edge is held in the Capture
Timer Data Register. That is, if multiple edges have occurred
before reading the capture timer, the time for the last one will
be read (default state).
The First Edge Hold function applies globally to all four cap-
ture timers.
Three prescaler bits allow the capture timer clock rate to be
selected among 5 choices, as shown in
Each of the four Capture Timer registers can be individually
enabled to provide interrupts.

Both Capture A events share a common interrupt request, as
do the two Capture B events. In addition to the event enables,
the main Capture Interrupt Enables bit in the Global Interrupt
Enable register (Section ) must be set to activate a capture
interrupt.
1 = Enable interrupt
0 = Disable interrupt
