The register contents can be read by writing the 8-bit hex address into the "Address" field

and the number of registers to be read in the "Length" field. Then click on the "Read" button.

The contents displayed are in Hex and 8-bits wide. The same procedure can be followed for

writing into the registers. The content to be written should be in bytes and only 8 bytes can

be written with a single "Write" button click.

Note:

The Length field should always be non-zero. A read or write with length zero causes the GUI

to close.
