Read-Modify-Write:
X- or Y-address is incremented after reading from or writing data to the display
RAM at normal mode. However, X- or Y-address is not incremented after reading data from the display
RAM at read-modify-write mode. The data which is read from the display RAM may be modified and
written to the same address without resetting the address. Data is temporarily latched into a HD66410’s
buffer and then output next time a read is performed in a subsequent cycle. This means that the dummy
read is necessary after every cycle. This sequence is shown in Figure 12.
