timer mode), 16-bit timer/event counter 0n continues counting up in synchronization with the count clock. When it has
counted up to FFFFH, the overflow flag (OVF0n) is set to 1 at the next clock, and TM0n is cleared (to 0000H) and
continues counting. Clear OVF0n to 0 by executing the CLR instruction via software.

When bits 3 and 2 (TMC0n3 and TMC0n2) of 16-bit timer mode control register 0n (TMC0n) are set to 01 (free-running
The following three types of free-running timer operations are available.
• Both CR00n and CR01n are used as compare registers.
• One of CR00n or CR01n is used as a compare register and the other is used as a capture register.
• Both CR00n and CR01n are used as capture registers.
Remarks 1. For the setting of the I/O pins, see 7.3 (5) Port mode register 0 (PM0).
