7.4.6 PPG output operation
(Programmable Pulse Generator) signal during a cycle set by CR00n when bits 3 and 2 (TMC0n3 and TMC0n2) of 16-
bit timer mode control register 0n (TMC0n) are set to 11 (clear & start upon a match between TM0n and CR00n).
A square wave having a pulse width set in advance by CR01n is output from the TO0n pin as a PPG
The pulse cycle and duty factor of the pulse generated as the PPG output are as follows.
• Pulse cycle = (Set value of CR00n + 1) × Count clock cycle
• Duty = (Set value of CR01n + 1) / (Set value of CR00n + 1)
Caution To change the duty factor (value of CR01n) during operation, see 7.5.1 Rewriting CR01n during
