pin valid edge input)
Set the clear & start mode entered by the TI000 pin valid edge (TMC003 and TMC002 = 10). The count value of
TM00 is captured to CR000 in the phase reverse to the valid edge of the TI000 pin, and the count value of TM00 is
captured to CR010 and TM00 is cleared (0000H) when the valid edge of the TI000 pin is detected. Therefore, a cycle
is stored in CR010 if TM00 does not overflow.
If an overflow occurs, take the value that results from adding 10000H to the value stored in CR010 as a cycle. Clear
bit 0 (OVF00) of 16-bit timer mode control register 00 (TMC00) to 0.
