Connecting a PSD3XX to an 8-Bit Multiplexed-Bus MCU Your 8-bit MCU PSD3XX PA PB PC AD0 -AD7 A8 -A15 ALE/AS PSEN R/ W or WR RD/E / DS1 A19 / CSI RESET A16-A182 Figure 3B. Connecting a PSD3XX to a 16-Bit Multiplexed-Bus MCU Your 16-bit MCU PSD3XX PA PB PC AD0 -AD7 AD8 -AD15 ALE/AS BHE/ PSEN R/ W or WR RD/E / DS1 A19 / CSI RESET A16-A182 Figure 3C. Connecting a PSD3XX to an 8-Bit Non-Multiplexed-Bus MCU Your 8-bit MCU PSD3XX PA PB PC D0 -D7 A0-A15 ALE/AS PSEN R/ W or WR RD/E / DS1 A19 / CSI RESET A16-A182 Figure 3D. Connecting a PSD3XX to a 16-Bit Non-Multiplexed-Bus MCU Your 16-bit MCU PSD3XX PA PB PC D0 -D15 A0-A15 ALE/AS BHE / PSEN R/ W or WR RD/E / DS1 A19 / CSI RESET A16-A182 D0 -D7 D8-D15 NOTES: 1. DS is a valid input on 3X2/3X3 and devices only. 2. Connect A16-A18 to Port C if your MCU outputs more than 16 bits of address. 8.0 Operating Modes (MCU Configurations) (cont.) |
