Data Transfer
The KS0741 uses bus holder and internal data bus for data transfer with the MPU. When writing data from the MPU
to on-chip RAM, data is automatically transferred from the bus holder to the RAM as shown in figure 5. And when
reading data from on-chip RAM to the MPU, the data for the initial read cycle is stored in the bus holder (dummy
read) and the MPU reads this stored data from bus holder for the next data read cycle as shown in figure 6. This
means that a dummy read cycle must be inserted between each pair of address sets when a sequence of address
sets is executed. Therefore, the data of the specified address cannot be output with the read display data instruction
right after the address sets, but can be output at the second read of data.
