Serial Interface (PS =

)
When the KS0715 is active (CS1B = L & CS2 = H), serial data (DB7) and serial clock (DB6) inputs are enabled.
And when the KS0715 is not active, the internal 8-bit shift register and the 3-bit counter are reset. Serial data can
be read on the rising edge of serial clock (DB6) and converted into 8-bit parallel data on the eighth serial clock.
Serial data input is display data when RS is high and control data when RS is low. Since the clock signal (DB6) is
easy to be affected by the external noise caused by the line length, the operation check on the actual machine is
recommended.
BUSY FLAG
The busy flag indicates whether the KS0715 is operating or not. When DB7 is high in read status operation, this
device is in busy status and will accept only read status instruction. If the cycle time is correct, the microprocessor
does not need to check this flag before each instruction, which improves the microprocessor performance.
DATA TRANSFER
The KS0715 uses a bus holder and an internal data bus for data transfer with MPU. When writing data from the
MPU to the on-chip RAM, data is automatically transferred from the bus holder to the RAM as shown in Figure4.
When reading data from the on-chip RAM to MPU, the data for the initial read cycle is stored in the bus holder
(dummy read). Consequently, MPU reads this stored data from the bus holder for the next data read cycle, as
shown in Figure 5. This means that a dummy read cycle must be inserted between each pair of address sets when
a sequence of address sets is executed, so that the data of the specified address can be output with the read
display data instruction at the second read of data rather than right after the address sets.
