3.1.9 Serial interface (SIO)
Four channels are comprised of two kinds of serial interfaces: an asynchronous serial interface (UART) and a clock-
synchronized serial interface (CSI). Two of these four channels are switchable between the UART and CSI and the
other two channels are fixed as CSI.
For UART, data is transferred via the TXD and RXD pins. The baud rate is determined by the on-chip baud rate
generator. For CSI, data is transferred via the SO, SI, and SCK pins. The baud rate can be determined by the on-
chip baud rate generator or it can be supplied from an external source.
One of the two CSI-fixed channels is used as the serial clock output, and serial output is sent via an N-ch open
drain output.
3.1.10 Pulse width modulation (PWM)
There are two channels of selectable 8/9/10/12-bit resolution PWM signal outputs. When a low pass filter is
externally connected, PWM output can be used as D/A converter output. This is suitable for actuator control
applications, such as in motors.
3.1.11 A/D converter (ADC)
This is a high-speed, high-resolution 10-bit A/D converter that includes eight analog input pins. It converts using
the sequential conversion method.
3.1.12 D/A converter (DAC)
This is an 8-bit resolution D/A converter that includes two channels. It converts using the R-2R conversion method.
