FUNCTIONAL DESCRIPTION
MICROPROCESSOR INTERFACE
Chip Select Input
There are CS1B for chip selection. The S6B0755 can interface with an MPU only when CS1B is "L" . 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
S6B0755 has four types of interface with an MPU, which are two serial and two parallel interface. This parallel or
serial interface is determined by PS 0pin as shown in Table 6.

Parallel Interface (PS0 = "H")
The 8-bit bi-directional data bus is used in parallel interface and the type of MPU is selected by PS1 as shown in
Table 7. The type of data transfer is determined by signals at RS, E_RD and RW_WR as shown in Table 8.

NOTE: When E_RD pin is always pulled high for 6800-series interface, it can be used CSB for enable signal. In
this case, interface data is latched at the rising edge of CSB and the type of data transfer is determined by
signals at RS, RW_WR as in case of 6800-series mode.
