 Up/Down-count Mode (Active-High) 
When Up/Down-count mode (Active-High) is selected, the following operation applies. 
If FRT is up-counting, the output level of RT(0) signa l is changed to Active level (High), when FRT’s count 
value matches OCCP(0). If FRT is  down-counting, the output level is changed to Inactive level (Low), 
when FRT’s count value matches OCCP(0). When 0x0000 is set to OCCP(0), all-active (High) is output, 
and then, it returns to Inactive...

When Up/Down-count mode (Active- Low) is selected, the following operation applies. 
If FRT is up-counting, the output level of RT(0) signa l is changed to Active level (Low), when FRT’s count 
value matches OCCP(0). If FRT is  down-counting, the output level is changed to Inactive level (High), 
when FRT’s count value matches OCCP(0). When 0x000 0 is set to OCCP(0), all-active (Low) is output,

 Through Mode 
The operation in Through mode is as follows (see the List of Output Details). 
The output of the CH_GATE signal is always fixed to the Low level. 
The RTO(1) and RTO(0) signals output the RT(1), RT(0), and CH_PPG signals through without change by 
PGEN[1:0] setting. 
Figure 4-19  shows an example of the operation waveform in Through mode of WFG-ch.10. In this example, 
th e RT0 signal an

 Timer PPG Mode 
The operation in Timer-PPG mode is as follows (see the List of Output Details). 
Each channel of WFG has two flags: WFG timer ac tive flag0 and WFG timer active flag1. This mode 
outputs a waveform using these flags. 
The CH_GATE signal outputs WFG timer active flag1,  WFG timer active flag0, or the logic OR signal of 
each signal by GTEN[1:0] setting. 
The RTO(1) and RTO(0) signals output these active fl ags, CH_PPG signal, or the logic AND...

 RT Dead Timer Mode 
The operation in RT dead timer mode is as follows (see the List of Output Details). 
The output of the CH_GATE signal is always fixed to the Low level. 
As for the RTO(1) and RTO(0) sign als, the non-overlap signal that has the dead time set by WFG timer 
based on the RT(1) signal is output. 
In this mode, the RT(0) signal and the CH_PPG signal are not used. This mode assumes that the output 
polarity of OCU’s RT(1) output is Active High. The...

 PPG Dead Timer Mode 
The operation in PPG dead timer mode is as  follows (see the List of Output Details). 
The CH_GATE signal outputs the RT(1) signal, RT(0) signal or logic OR signal by GTEN[1:0] setting. 
As for the RTO(1) and RTO(0) sign als, the non-overlap signal that has the dead time set by WFG timer 
based on the CH_PPG signal is output. 
In this mode, the RT(0) and RT(1) signals are used only for the output of the CH_GATE signal.
