6.4.5 Free-running timer operation
running timer mode), 16-bit timer/event counter 00 continues counting up in synchronization with the count clock.
When it has counted up to FFFFH, the overflow flag (OVF00) is set to 1 at the next clock, and TM00 is cleared (to
0000H) and continues counting. Clear OVF00 to 0 by executing the CLR instruction via software.

When bits 3 and 2 (TMC003 and TMC002) of 16-bit timer mode control register 00 (TMC00) are set to 01 (free-
The following three types of free-running timer operations are available.
Remarks 1. For the setting of the I/O pins, refer to 6.3 (5) Port mode register 0 (PM0).
(CR000: compare register, CR010: compare register)
Both CR000 and CR010 are used as compare registers.
One of CR000 or CR010 is used as a compare register and the other is used as a capture register.
Both CR000 and CR010 are used as capture registers.
