1 : Free-run type
Reserved bit
Must always be set to “0”
Notes 1: In event counter mode, the count source is selected by the event / trigger
select bit (addresses 038216 and 038316).
2: The settings of the corresponding port register and port direction register
are invalid.
3: This bit of TAiMR (i = 0, 1, 4) must always be set to “0.”
4: When an “L” signal is input to the input signal from TA2OUT/TA3OUT pin,
the downcount is activated. When “H,” the upcount is activated. Set the
corresponding port direction register to “0.”
