| Timers |
| 8-bit timer |
3 ch |
RTC |
- Choice of eight internal clock sources
- Can operate as a one-week real-time clock (RTC) incorporating a crystal oscillator.
|
| Timer B1 |
- Selection of seven internal clock sources (φ/8192, φ/2048, φ/512, φ/256, φ/64, φ/16, and φ/4) or an external clock (can be used to count external events).
- Internal data bus
- An interrupt is generated when the counter overflows.
|
| Timer V |
- Choice of seven clock signals is available. Choice of six internal clock sources (φ/128, φ/64, φ/32, φ/16, φ/8, φ/4) or an external clock.
- Counter can be cleared by compare match A or B, or by an external reset signal. If the count stop function is selected, the counter can be halted when cleared.
- Timer output is controlled by two independent compare match signals, enabling pulse output with an arbitrary duty cycle, PWM output, and other applications.
- Three interrupt sources: compare match A, compare match B, timer overflow
- Counting can be initiated by trigger input at the TRGV pin. The rising edge, falling edge, or both edges of the TRGV input can be selected.

| 16-bit timer |
2 ch |
Timer Z |
- Capability to process up to eight inputs/outputs
- Eight general registers (GR): Four registers for each channel
- Independently assignable output compare or input capture functions
- Selection of five counter clock sources: Four internal clocks (φ, φ/2, φ/4, and φ/8) and an external clock
- Seven selectable operating modes
- High-speed access by the internal 16-bit bus
-16-bit TCNT and GR registers can be accessed in high speed by a 16-bit bus interface
- Any initial timer output value can be set.
- Output of the timer is disabled by external trigger.
