8.3.5 Input Capture Registers
When a selected edge occurs on the TCAP pin, the current high and low bytes of the 16-bit counter are
latched into the input capture registers. Reading ICRH before reading ICRL inhibits further capture until
ICRL is read. Reading ICRL after reading the status register clears the input capture flag (ICF). Writing to
the input capture registers has no effect.
NOTE
To prevent interrupts from occurring between readings of ICRH and ICRL,
set the interrupt flag in the condition code register before reading ICRH, and
clear the flag after reading ICRL.
8.3.6 Output Compare Registers
When the value of the 16-bit counter matches the value in the output compare registers, the planned
TCMP pin action takes place. Writing to OCRH before writing to OCRL inhibits timer compares until OCRL
is written. Reading or writing to OCRL after the timer status register clears the output compare flag (OCF).
