6.4.6 PPG output operation
Pulse Generator) signal during a cycle set by CR000 when bits 3 and 2 (TMC003 and TMC002) of 16-bit timer mode
control register 00 (TMC00) are set to 11 (clear & start upon a match between TM00 and CR000).

A square wave having a pulse width set in advance by CR010 is output from the TO00 pin as a PPG (Programmable
The pulse cycle and duty factor of the pulse generated as the PPG output are as follows.
• Pulse cycle = (Set value of CR000 + 1) × Count clock cycle
• Duty = (Set value of CR010 + 1) / (Set value of CR000 + 1)
Caution To change the duty factor (value of CR010) during operation, refer to 6.5.1 Rewriting CR010 during
