CHAPTER 21 MULTI-PULSE GENERATOR
21.2 Block Diagram
● 16-bit reload timer
The 16-bit reload timer is used to act as the interval timer for the waveform sequencer. Details
of the 16-bit reload timer are described in "CHAPTER 20 16-BIT RELOAD TIMER".
● Waveform sequencer
The waveform sequencer is the core of the multi-pulse generator, which can generate various
waveforms. Its block diagram is shown in Figure 21.2-2.
