How to fix 1 bit misalignment using synchronous mode and clock SCI?
The serial interface of the H8 family and the H8S family is divided into a transmit part and a receive part structurally to be used for both asynchronous and functions. The transmit part and the receive part can be operated individually. When in synchronous transmit/receive data, each part ...

How to properly set up A/D converter?
Depending on the operating frequency and the setting value that you are using, it can be possible to setup the conversion time, which is lower than the minimum conversion time of electrical characteristics, but in that case, accurate conversion result will not be guaranteed. All the A/D converters ...

Why does an error occurs in asynchronous mode when starting RxD pin?
For the serial interface in the H8 and H8S family, when a receive pin (a RxD pin) is low, start the receive operation to receive a break signal at the time the low pin was detected. Next, a framing error occurs when the serial interface could not detect the STOP ...
