6.4.7 One-shot pulse output operation
register 00 (TMC00) to 01 (free-running timer mode) or to 10 (clear & start mode entered by the TI000 pin valid edge)
and setting bit 5 (OSPE00) of 16-bit timer output control register 00 (TOC00) to 1.
clearing & starting of TM00 is triggered, and a pulse of the difference between the values of CR000 and CR010 is
output only once from the TO00 pin.
A one-shot pulse can be output by setting bits 3 and 2 (TMC003 and TMC002) of the 16-bit timer mode control
When bit 6 (OSPT00) of TOC00 is set to 1 or when the valid edge is input to the TI000 pin during timer operation,
Cautions 1. Do not input the trigger again (setting OSPT00 to 1 or detecting the valid edge of the TI000
Remarks 1. For the setting of the I/O pins, refer to 6.3 (5) Port mode register 0 (PM0).
