7.2.2 PPG output operation
(TMCn) and capture/compare control register n (CRCn) as shown in Figure 7-5.
advance to 16-bit capture/compare register n0 (CRn0) and the pulse width specified by the count value set in advance
to 16-bit capture/compare register n1 (CRn1).

TMCn
CRCn
TOCn
TMn can be used for PPG (Programmable Pulse Generator) output by setting 16-bit timer mode control register n
The PPG output function outputs a square wave from the TOn pin at the cycle specified by the count value set in
Remark
Cautions 1. Make sure that CRn0 and CRn1 are set to 0000H < CRn1 < CRn0 ≤ FFFFH.
n = 0, 1

2. PPG output set the pulse cycle to (CRn0 set value + 1).
The duty factor is (CRn1 set value + 1)/(CRn0 set value + 1).
