Section 14 Timer Unit (TMU)
14.5
14.5.1
Synchronization processing is not performed for timer counting during register writes. When
writing to registers, always clear the appropriate start bits for the channel (STR2 to STR0) in the
timer start register (TSTR) to halt timer counting.
14.5.2
Synchronization processing is performed for timer counting during register reads. When timer
counting and register read processing are performed simultaneously, the register value before
TCNT counting down with synchronization processing is read.
