6. FUNCTION DESCRIPTION
MPU Interface
Selection of interface type
The S1D15710 series transfers data through 8-bit bidirectional data buses (D7 to D0) or serial data input (SI). By setting
the polarity of the P/S pin to either HIGH or LOW, the 8-bit parallel data entry or serial data entry can be selected as
listed in Table 1.
Parallel interface
When the parallel interface is selected (P/S=HIGH), the S1D15705 series can directly be connected to the MPU bus
of either the 80 or 68 series MPU by setting the C86 pin to HIGH or LOW as listed in Table 2.
In addition, the data bus signal can be identified according to the combinations of the A0, RD (E), WR (R/W) signals
as listed in Table 3.
