in Figure 6-15 allows operation as PPG (Programmable Pulse Generator) output.
correspond to the count values preset in 16-bit capture/compare register 01n (CR01n) and in 16-bit capture/compare
register 00n (CR00n).

Setting 16-bit timer mode control register 0n (TMC0n) and capture/compare control register 0n (CRC0n) as shown
In the PPG output operation, square waves are output from the TO0n pin with the pulse width and the cycle that
Remark n = 0, 1
Remark
Cautions 1. Values in the following range should be set in CR00n and CR01n:
TMC0n
CRC0n
TOC0n
n = 0, 1
2. The cycle of the pulse generated by PPG output becomes (CR00n setting + 1), and the duty
