3.6V) |
| Input-only pins |
8 input pins |
|
| Timers |
| RTC |
- Choice of eight internal clock sources
- Counts seconds, minutes, hours, and day-of-week
- Can be used as 8-bit free running counter
|
| Asynchronous Event Counter (AEC) |
16-bit timer |
- Count-up timer able to count asynchronous external events independently of
the MCUs internal clock
|
| Timer F |
16-bit timer |
- Choice of five counter input clocks
Internal clocks (φ/32, φ/16, φ/4, and φW/4) or external clocks can be
selected.
- Toggle output function.
|
| Timer Pulse Unit (TPU) |
16-Bit Timer Unit x 2ch |
- Maximum 4-pulse input/output.
- Selection of 7 or 8 counter input clocks for each channel
- Waveform output at compare match
- Input capture function
- PWM output with any duty level is possible
- Operation with cascaded connection
|
| 14-Bit PWM x 4ch |
- Choice of four conversion periods
- Pulse division method for less ripple.
- Use of module standby mode enables this module to be placed in standby mode
independently when not used.
- The standard PWM or pulse-division type PWM can be selected by
software.
|
| Watchdog Timer |
- Selectable from eleven counter input clocks
- Watchdog timer mode
- Interval timer mode
- Use of module standby mode enables this module to be placed in standby mode
independently when not used.
