78K0/Kx2-L
7.4.3 Square-wave output operation
register 5n (CR5n).
(TOE5n) of 8-bit timer mode control register 5n (TMC5n) to 1. This enables a square wave with any selected frequency to
be output (duty = 50%).

Sep 27, 2010
A square wave with any selected frequency is output at intervals determined by the value preset to 8-bit timer compare
The TO5n pin output status is inverted at intervals determined by the count value preset to CR5n by setting bit 0
Remark Square-wave output is operable only in the 78K0/KB2-L and 78K0/KC2-L.
<1> Set each register.
<2> After TCE5n = 1 is set, the count operation starts.
<3> The timer output F/F is inverted by a match of TM5n and CR5n. After INTTM5n is generated, TM5n is cleared to
<4> After these settings, the timer output F/F is inverted at the same interval and a square wave is output from TO5n.
Note 8-bit timer/event counter 50: P17, PM17
Caution Do not write other values to CR5n during operation.
Remarks 1. For how to enable the INTTM5n signal interrupt, refer to CHAPTER 17 INTERRUPT FUNCTIONS.
Setting
• Clear the port output latch (P17 or P33)
• TCL5n: Select the count clock.
• CR5n:
• TMC5n: Stop the count operation, select the mode in which clear & start occurs on a match of TM5n and
00H.
The frequency is as follows.
• Frequency = 1/2t (N + 1)
