Mode 3 Input Capture Mode
The device can precisely measure external frequencies or
time external events by placing the timer block Tx in the
input capture mode
In this mode the timer Tx is constantly running at the fixed
tc rate The two registers RxA and RxB act as capture
registers Each register acts in conjunction with a pin The
register RxA acts in conjunction with the TxA pin and the
register RxB acts in conjunction with the TxB pin
flow interrupt pending flag in the Input Capture mode) Con-
sequently the TxC0 control bit should be reset when enter-
ing the Input Capture mode The timer underflow interrupt is
enabled with the TxENA control flag When a TxA interrupt
occurs in the Input Capture mode the user must check both
whether a TxA input capture or a timer underflow (or both)
caused the interrupt
Figure 8 shows a block diagram of the timer in Input Capture
mode
The timer value gets copied over into the register when a
