Programmable I/O pins.

3.3-V supply voltage for core logic and I/O signals.

Ground for core logic and I/O signals.

3.3-V supply voltage for core logic and I/O signals.

Ground for core logic and I/O signals.

Host address bus. 3-bit address bus selects one of eight host interface registers.

Host chip select. Host asserts CS to select the decoder for a read or write operation. The falling edge of this signal

triggers the read of write operation.

Read/write strobe in M mode. Write strobe in I mode. Host asserts R/W LOW to select write and LOW to select Read.

Read strobe in I mode. Must be held HIGH in M Mode.

NOTE:

•

-XX, -X mean standardized parts, so they may
have some differences from the original one.

•

Items marked “*” are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering these
items.

•

The mechanical parts with no reference number
in the exploded views are not supplied.

•

Hardware (# mark) list and accessories and
packing materials are given in the last of this
parts list.

The components identified by mark
