80C251
The Intel 80C251 MCU features a user-config-
urable bus interface with four possible bus config-
urations, as shown in
Table 18., page 48
.
The first configuration is 80C31-compatible, and
the bus interface to the PSD is identical to that
shown in
Figure 21., page 46
. The second and
third configurations have the same bus connection
as shown in Figure
22
. There is only one Read
Strobe (PSEN) connected to CNTL1 on the PSD.
The A16 connection to PA0 allows for a larger ad-
dress input to the PSD. The fourth configuration is
shown in
Figure 23., page 48
. Read Strobe (RD) is
connected to CNTL1 and Program Select Enable
(PSEN) is connected to CNTL2.
The 80C251 has two major operating modes:
Page mode and Non-page mode. In Non-page
mode, the data is multiplexed with the lower ad-
dress byte, and Address Strobe (ALE/AS, PD0) is
active in every bus cycle. In Page mode, data (D7-
D0) is multiplexed with address (A15-A8). In a bus
cycle where there is a Page hit, Address Strobe
(ALE/AS, PD0) is not active and only addresses
(A7-A0) are changing. The PSD supports both
modes. In Page Mode, the PSD bus timing is iden-
tical to Non-Page Mode except the address hold
time and setup time with respect to Address
Strobe (ALE/AS, PD0) is not required. The PSD
access time is measured from address (A7-A0)
valid to data in valid.

Note: 1. The A16 and A17 connections are optional.
2. In non-Page-Mode, AD7-AD0 connects to ADIO7-ADIO0.
