I
The signals used for the Intel microprocessor interface are: Address Latch Enable (ALE), Read Enable (RD),
Write Enable (WR), Chip Select (CS), Address and Data bits. The microprocessor interface uses minimum ex-
ternal glue logic and is compatible with the timings of the 8051 or 80C188 with an 8-16 MHz clock frequency,
and with the timings of x86 or i960 family or microprocessors. The interface timing shown in
