Timer/counter function
16-bit timer for 3-phase sine wave PWM inverter control: 2 channels
16-bit up/down counter/timer for 2-phase encoder input: 1 channel
General-purpose 16-bit timer/counter: 2 channels
General-purpose 16-bit timer/event counter: 1 channel
16-bit interval timer: 1 channel
Serial interface
Asynchronous serial interface (UART): 2 channels
Clocked serial interface (CSI): 2 channels
Of the four channels, two channels are used for both CSI and UART and therefore
one or the other function must be selected.
A/D converter
10-bit resolution A/D converter: 6 ch 8 channels (2 units)
Regulator
Two power supplies, one for the internal CPU and one for the peripheral interface, are
not necessary. A 5 V single-power-supply system can be configured by connecting an
N-ch transistor (2SD1950 (VL standard product, surface mount type) or 2SD1581
(independent type) is recommended). If a 3.3 V power supply is available, it can be
directly connected to the REGIN pin.
