This section shows a typical interface circuit between the ISP1160 and a RISC
processor. The Hitachi SH-3 series RISC processor SH7709 is used as the example.
The main ISP1160 signals to be taken into consideration for connecting to a SH7709
RISC processor are:
5 V
•
•
•
•
A 16-bit data bus: D[15:0] for the ISP1160. The ISP1160 is ‘little endian’
compatible.
The address line A0 is needed for a complete addressing of the ISP1160 internal
registers:
The CS_N line is used for chip selection of the ISP1160 in a certain address range
of the RISC system. This signal is active LOW.
RD_N and WR_N are common read and write signals. These signals are active
LOW.
