FUNCTION DESCRIPTION
MICROPROCESSOR INTERFACE
CHIP SELECT INPUT
There are CS1B and CS2 pins for chip selection. The KS0717 can interface with a microprocessor only when
CS1B is low and CS2 is high. When these pins are set to any other combination, RS, E_RD, and RW_WR inputs
are disabled and DB0 to DB7 are to be high impedance. In case of serial interface, the internal shift register and
the counter are reset.
PARALLEL / SERIAL INTERFACE
KS0717 has three types of interface with MPU, one serial and two parallel. This parallel or serial interface is
determined by PS pin as shown in Table 3.

Parallel interface (PS =

)
The 8-bit bidirectional data bus is used in parallel interface and the type of MPU is selected by C68 as shown in
Table 4. The type of data transfer is determined by signals at RS, E_RD and RW_WR as shown in Table 5.
