RL78/L12 CHAPTER 6 TIMER ARRAY UNIT

Dec 13, 2013
The timer array unit has eight 16-bit timers.
Each 16-bit timer is called a channel and can be used as an independent timer. In addition, two or more “channels” can
be used to create a high-accuracy timer.

(→ refer to 6.8.3)
• Input pulse interval measurement (→ refer to 6.8.4)
• Measurement of high-/low-level width of input signal
(→ refer to 6.8.5)
• Delay counter (→ refer to 6.8.6)
• One-shot pulse output(→ refer to 6.9.1)
• PWM output(→ refer to 6.9.2)
• Multiple PWM output(→ refer to 6.9.3)

Notes 1. Only channel 0.
2. 44, 48, 52, 64-pin products only.
It is possible to use the 16-bit timer of channels 1 and 3 as two 8-bit timers (higher and lower). The functions that can
use channels 1 and 3 as 8-bit timers are as follows:
• Interval timer (upper or lower 8-bit timer)/square wave output
• External event counter (lower 8-bit timer only)
• Delay counter (lower 8-bit timer only)
Channel 5 can be used to realize LIN-bus communication operating in combination with UART0 of the serial array unit.
