6.4.6 PPG output operation
(Programmable 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
The pulse cycle and duty factor of the pulse generated as the PPG output are as follows.
Caution To change the duty factor (value of CR010) during operation, see 6.5.1 Rewriting CR010 during
Remarks 1. For the setting of I/O pins, see 6.3 (6) Port mode register 3 (PM3).
Pulse cycle = (Set value of CR000 + 1)
Duty = (Set value of CR010 + 1) / (Set value of CR000 + 1)
