USER’S MANUAL
Table D-45
Eight-bit read/write counter used for external event counting or gated time accumula-
tion.
The input capture registers are 16-bit read-only registers used to latch the value of
TCNT when a specified transition is detected on the corresponding input capture pin.
They are reset to $FFFF.
The output compare registers are 16-bit read/write registers which can be used as out-
put waveform controls or as elapsed time indicators. For output compare functions,
they are written to a desired match value and compared against TCNT to control spec-
ified pin actions. They are reset to $FFFF.
0 = Output compare 5 enabled
1 = Input capture 4 enabled
shows the PACLK[1:0] bit field effects.
