Cautions 1. 16-bit timer counter 0 starts operating as soon as a value other than 0, 0 (operation stop
mode) has been set to TMC02 and TMC03.
2. The software trigger (bit 6 (OSPT) of 16-bit timer output control register 0 (TOC0) = 1) and
the external trigger (TI00 input) are always valid in one-shot pulse output mode.
If the software trigger is used in one-shot pulse output mode, the TI00 pin cannot be used
as a general-purpose port pin. Therefore, fix the TI00 pin to either high level or low level.
