register n (CRn).
inverted at an interval specified by the count value preset in the CRn register. In this way, a square wave of any
frequency can be output (duty = 50%) (n = 2 to 5).
A square wave with any frequency can be output at an interval specified by the value preset in 8-bit timer compare
By setting the TOEn bit of 8-bit timer mode control register n (TMCn) to 1, the output status of the TOn pin is
Setting method
<1> Set each register.
<2> When the TMCEn bit of the TMCn register is set to 1, counting starts.
<3> When the values of the TMn register and CRn register match, the timer output F/F is inverted.
<4> Then, the timer F/F is inverted during the same interval and a square wave is output from the TOn pin.
Square-wave output operation (8-bit resolution)
Caution Do not rewrite the value of the CRn register during square-wave output.
• TCLn register: Selects the count clock (t).
• CRn register:
• TMCn register: Stops count operation, selects the mode in which clear & start occurs on a match
Moreover, INTTMn is generated and the TMn register is cleared to 00H.
Compare value (N)
between the TMn register and CRn register.
