3.7 REALTIME PULSE UNIT (RPU)
This unit can measure pulse intervals and frequencies, and generate programmable pulse outputs.
It consists mainly of two timers. To flexibly cope with many applications, the configuration of registers connected to the
timers can be changed using programs. To meet various applications, toggle output (6 max.) or set/reset output (4 max.)
can be selected as timer output.
3.7.1 Configuration
The realtime pulse unit is configured mainly of timer 0 (TM0) which functions as a 16-bit or 18-bit free running timer and
timer 1 (TM1) which functions as a 16-bit timer/event counter shown in Figure 3-3.
