FUNCTIONAL DESCRIPTION
MICROPROCESSOR INTERFACE
Chip Select Input
There are CS1B and CS2 pins for Chip Selection. The S6B1713 can interface with an MPU only when CS1B is “L”
and CS2 is “H”. 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. And, in case of serial interface, the internal shift register and the counter are
reset.
Parallel / Serial Interface
S6B1713 has three types of interface with an MPU, which are one serial and two parallel interfaces. This parallel or
serial interface is determined by PS pin as shown in table 8.

Parallel Interface (PS = "H")
The 8-bit bi-directional data bus is used in parallel interface and the type of MPU is selected by MI as shown in table
9. The type of data transfer is determined by signals at RS, E_RD and RW_WR as shown in table10.
