Real-time pulse unit (RPU)
This unit has 3 channels of 16-bit multi purpose timer/event counter and 2 channels of 16-bit inter-
val timer built in, and it is possible to measure pulse widths or frequency and to output a program-
mable pulse.

Serial interface (SIO)
A 2-channel asynchronous serial interface (UART), 3-channel clocked serial interface (CSI), and
4-channel FCAN are provided as serial interface.
UART transfers data by using the TXDn and RXDn pins. (n = 0 - 1)
CSI transfers data by using the SOn, SIn, and SCKn pins. (n = 0 - 2)
FCAN performs data transfer using CTXDn and CRXDn pins. (n = 1 - 4)
(10) A/D converter (ADC)
One high-resolution 10-bit A/D converter, it includes 12 analog input pins. Conversion uses the
successive approximation method.
