PWC
Pulse width counter timer : 2 channels
Pulse width counter 
timer :  1ch
Timer function (select the counter timer from three internal clocks) 
Various Pulse width measuring function (H pulse width, L pulse width, rising edge to fall-
ing edge period, falling edge to rising edge period, rising edge to rising edge period and 
falling edge to falling edge period) 
UART : 2 channels
With full-duplex double buffer (8-bit length) 
Clock asynchronized or clock synchronized transmission (with start and stop bits) can 
be selectively used
Transmission can be one-to-one (bi-directional commuication) or one-to-n (Master-
Slave communication) 
Reload timer : 2 channels
Reload mode, single-shot mode or event count mode selectable
Can be worked with a multi-pulse generator or individually
PPG timer : 3 channels
PWM mode or single-shot mode selectable
Can be worked with multi-functional timer / multi-pulse generator or individually
16-bit free-running timer with up or up/down mode selection and buffer : 1 channel
16-bit output compare : 6 channels
16-bit input capture : 4 channels
16-bit PPG timer : 1 channel
Waveform generator (16-bit timer : 3 channels, 3-phase waveform or dead time) 
16-bit PPG timer : 1 channel
16-bit reload timer operation (toggle output, one shot output select-
able) 
Event counter function : 1 channel built-in
A waveform sequencer (includes 16-bit timer with buffer and com-
pare clear function) 
8/10-bit resolution (8 channels)
