c) 90° Turning Circuit
1. Write, in the 90° turning data buffer which extends from Address XX08h to XX0Fh, the data to be turned.
2. In the same way, with XX08h XX0Fh being read, data which have been turned by 90° can be obtained. This is
highly convenient as both rightward and leftward turning is freely available by the writing and reading order.

rightward turning is produced.
