19. Timer RC
19.7 PWM2 Mode
This mode outputs a single PWM waveform. After a given wait duration has elapsed following the trigger, the pin
output switches to active level. Then, after a given duration, the output switches back to inactive level.
Furthermore, the counter stops at the same time the output returns to inactive level, making it possible to use
PWM2 mode to output a programmable wait one-shot waveform.
Since timer RC uses multiple general registers in PWM2 mode, other modes cannot be used in conjunction with it.
Figure 19.16 shows a PWM2 Mode Block Diagram, Table 19.13 lists the Specifications of PWM2 Mode, Table
19.14 lists the Functions of TRCGRj Register in PWM2 Mode, and Figures 19.17 to 19.19 show Operating
Examples of PWM2 Mode.
