RX210 Group 1. Overview
Timers 16-bit timer pulse unit
(TPUa)
(16 bits × 6 channels) × 1 unit
Maximum of 16 pulse-input/output possible
Select from among seven or eight counter-input clock signals for each channel
Supports the input capture/output compare function
Output of PWM waveforms in up to 15 phases in PWM mode
Support for buffered operation, phase-counting mode (two-phase encoder input) and cascade-
connected operation (32 bits × 2 channels) depending on the channel.
Capable of generating conversion start triggers for the A/D converters
Signals from the input capture pins are input via a digital filter
Clock frequency measuring method
(Products with 144 or more pins incorporate a TPU.)
Multi-function timer pulse
unit 2 (MTU2a)
(16 bits 6 channels) 1 unit
Up to 16 pulse-input/output lines and three pulse-input lines are available with six 16-bit timer
channels
Select from among eight or seven counter-input clock signals for each channel (PCLK/1, PCLK/4,
PCLK/16, PCLK/64, PCLK/256, PCLK/1024, MTCLKA, MTCLKB, MTCLKC, MTCLKD) other than
channel 5, for which only four signals are available.
Input capture function
21 output compare/input capture registers
Pulse output mode
Complementary PWM output mode
Reset synchronous PWM mode
Phase-counting mode
Generation of triggers for A/D converter conversion
Port output enable 2
(POE2a)
Controls the high-impedance state of the MTU’s waveform output pins
8-bit timer (TMR)
(8 bits 2 channels) 2 units
Select from among seven internal clock signals (PCLK1, PCLK/2, PCLK/8, PCLK/32, PCLK/64,
PCLK/1024, PCLK/8192) and one external clock signal
Capable of output of pulse trains with desired duty cycles or of PWM signals
The 2 channels of each unit can be cascaded to create a 16-bit timer
Capable of generating baud-rate clocks for SCI5, SCI6, and SCI12
Compare match timer
(CMT)
(16 bits 2 channels) 2 units
Select from among four clock signals (PCLK/8, PCLK/32, PCLK/128, PCLK/512)
Watchdog timer (WDTA)
14 bits 1 channel
Select from among six counter-input clock signals (PCLK/4, PCLK/64, PCLK/128, PCLK/512,
PCLK/2048, PCLK/8192)
Independent watchdog
timer (IWDTa)
14 bits 1 channel
Counter-input clock: IWDT-dedicated on-chip oscillator
Frequ
ency di
vided by 1, 16, 32, 64, 128, or 256
Realtime clock (RTCb)
Clock source: Sub-clock
Time/calendar
Interrupt sources: Alarm interrupt, periodic interrupt, and carry interrupt
Time-capture facility for three values
