waveforms.
parallel-drive available for large current VFD.
- 16-step dimmer function available
(7) Weak signal detection (MIC signals etc)
- Counts pulses with width greater than a preset value
- 2 bit counter
(8) Timers
- Timer 0: 16 bit timer / counter with capture register
Mode 0: 2 channel 8-bit timer with programmable 8 bit prescaler and 8 bit capture register
Mode 1: 8 bit timer with 8 bit programmable prescaler and 8 bit capture register + 8 bit
Counter with 8-bit capture register
Mode 2: 16 bit timer with 8 bit programmable prescaler and 16 bit capture register
Mode 3: 16 bit counter with 16 bit capture register
- Timer 1: PWM / 16 bit timer toggle output
Mode 0: 2 channel 8 bit timer (with toggle output)
Mode 1: 2 channel 8 bit PWM
Mode 2: 16 bit timer (with toggle output) Toggle output also possible using lower order 8 bits.
Mode 3: 16 bit timer (with toggle output) Lower order 8 bits can be used as PWM output.
- Base Timer
1) The clock signal can be selected from any of the following :
Sub-clock (32.768kHz crystal oscillator), system clock, and prescaler output from timer 0
2) Interrupts can be selected to occur at one of five different times.
