10.3.3.3 Input Capture
In this section, the index, i, may be 1 or 2.
The two input capture 16-bit registers (IC1R and
IC2R) are used to latch the value of the free run-
ning counter after a transition detected by the
ICAPi pin (see figure 5).
ICi Rregister is a read-only register.
The active transition is software programmable
through the IEDGi bit of the Control Register (CRi).
Timing resolution is one count of the free running
counter: (
Procedure
To use the input capture function select the follow-
ing in the CR2 register:
– Select the timer clock (CC[1:0] (see

the ICIE bit in the CR1 register (in this case, the
IC1IE & IC2IE enable bits are not significant).
To enable only one ICAP interrupt, reset the ICIE
bit and set the IC1IE (or IC2IE) bit.
Note: If ICIE is reset and both IC1IE & IC2IE are
set, both interrupts are enabled.
In all cases, set the EFTIS bit to enable timer in-

Clearing the Input Capture interrupt request is
done by:
1. An access (read or write) to the SR register
2. An access (read or write) to the ICiLR register.
Note: After reading the ICiHR register, transfer of
input capture data is inhibited until the ICiLR regis-
ter is also read.
The ICiR register always contains the free running
counter value which corresponds to the most re-
cent input capture.

Note: If the ICIE bit is set, the status of the

nificant.

Otherwise, the interrupt remains pending until
the related enable bits are set.
