The description offered in this chapter is based on the R8C/L3AA Group and the R8C/L3AB Group.
For other groups, refer to 1.1.2 Differences between Groups.
Table 18.1
TRBO
Timer RA underflow
Timer RB is an 8-bit timer with an 8-bit prescaler.
The prescaler and timer each consist of a reload register and counter (refer to Tables 18.2 to 18.5 for the
Specifications of Each Mode) for accessing the reload register and counter. Timer RB has timer RB primary and
timer RB secondary as reload registers.
The count source for timer RB is the operating clock that regulates the timing of timer operations such as counting
and reloading.
Figure 18.1 shows the Timer RB Block Diagram. Table 18.1 lists the Timer RB Pin Configuration.
Timer RB supports the four operating modes:
• Timer mode:
• Programmable waveform generation mode:
• Programmable one-shot generation mode:
• Programmable wait one-shot generation mode:

Pulse output (programmable waveform generation
mode, programmable one-shot generation mode,
programmable wait one-shot generation mode)
The timer counts an internal count source (peripheral
function clock or timer RA underflows).
The timer outputs pulses of a given width successively.
The timer outputs a one-shot pulse.
The timer outputs a delayed one-shot pulse.
