external input signal can be selected simultaneously, by setting IEDGA ≠ IEDGC. If IEDGA =
IEDGC, then only one edge is selected (either the rising edge or falling edge). See table 9.16.
Note: The FRC value is transferred to the input capture register (ICR) regardless of the value of

ICRA to ICRD can be written and read by the CPU. Since they are 16-bit registers, data is
transferred from them to the CPU via a temporary register (TEMP). For details see section 9.5.3,
CPU Interface.
To assure input capture, the pulse width of the input capture input signal must be at least 1.5
system clocks ( ) when a single edge is selected, or at least 2.5 system clocks ( ) when both edges
are selected.
ICRA to ICRD are initialized to H'0000 upon reset and in standby mode, watch mode, subsleep
mode, and subactive mode.
