4.4Digital Input and Output
The
To program digital I/O operation is fairly straight forward. The digital input operation is just to read data from the corresponding registers, and the digital output operation is to write data to the corresponding registers. The digital I/O registers‘ format are shown in section 4.5. Note that the DIO data channel can only be read or written in form of 16 bits together. It is impossible to access individual bit channel.
