Operation Of Waveform Generator - Fujitsu MB90460 Series Hardware Manual

14.6.4

Operation of Waveform Generator

Waveform generator can produce various waveform such as dead-time, by using the
real-time outputs (RT0 to RT5), 16-bit PPG timer 0 and 16-bit timers 0/1/2.

*1 In order to generate non-overlap signal, be sure to select 2-channel mode for RT1/RT3/RT5 (OCS1/OCS3/
OCS5:CMOD=1)
*2 RTO0/RTO1 is controlled by DTCR0:TMD2 to TMD0, RTO2/RTO3 is controlled by DTCR1:TMD2 to TMD0 and
RTO4/RTO5 is controlled by DTCR2:TMD2 to TMD0.
