used for PPG output and the duty factor is changed. (When changing the value of CR01n to a smaller value than the
current one, rewrite it immediately after its value matches the value of TM0n. When changing the value of CR01n to a
larger value than the current one, rewrite it immediately after the values of CR00n and TM0n match. If the value of CR01n
is rewritten immediately before a match between CR01n and TM0n, or between CR00n and TM0n, an unexpected
operation may be performed.).

In principle, rewriting CR00n and CR01n of the 78K0/Kx2 microcontrollers when they are used as compare registers is
However, the value of CR01n can be changed, even while TM0n is operating, using the following procedure if CR01n is
Remark For TMIF01n and TMMK01n, see CHAPTER 20 INTERRUPT FUNCTIONS.
Procedure for changing value of CR01n
<1> Disable interrupt INTTM01n (TMMK01n = 1).
<2> Disable reversal of the timer output when the value of TM0n matches that of CR01n (TOC0n4 = 0).
<3> Change the value of CR01n.
<4> Wait for one cycle of the count clock of TM0n.
<5> Enable reversal of the timer output when the value of TM0n matches that of CR01n (TOC0n4 = 1).
<6> Clear the interrupt flag of INTTM01n (TMIF01n = 0) to 0.
<7> Enable interrupt INTTM01n (TMMK01n = 0).
LVS0n and LVR0n are used to set the default value of the TO0n output and to invert the timer output without enabling
the timer operation (TMC0n3 and TMC0n2 = 00). Clear LVS0n and LVR0n to 00 (default value: low-level output)
when software control is unnecessary.
