(ii) CMP01 register setting
Compare value (N)
<2>
Count operation starts when TMHE1 = 1.
<3>
When the values of 8-bit timer counter H1 and the CMP01 register match, the INTTMH1 signal is generated
and 8-bit timer counter H1 is cleared to 00H.
Interval time = (N +1)/fCNT
<4>
Subsequently, the INTTMH1 signal is generated at the same interval. To stop the count operation, clear
TMHE1 to 0.
(2) Timing chart
The timing of the interval timer/square-wave output operation is shown below.
