6. DESCRIPTION OF FUNCTIONS
The MPU Interface
Selecting the Interface Type
With the S1D15605 Series chips, data transfers are done
through an 8-bit bi-directional data bus (D7 to D0) or
The Parallel Interface
When the parallel interface has been selected (P/S =
HIGH), then it is possible to connect directly to either an
Moreover, data bus signals are recognized by a
combination of A0, RD (E), WR (R/W) signals, as
shown in Table 3.
