ST92F124/F150/F250 - EXTERNAL MEMORY INTERFACE (EXTMI)
EXTERNAL MEMORY SIGNALS (Cont’d)
8.2.5 PORT 0
If Port 0 is used as a bit programmable parallel I/O
port, it has the same features as a regular port.
When set as an Alternate Function, it is used as
the External Memory interface: it outputs the mul-
tiplexed Address (8 LSB: A[7:0]) / Data bus D[7:0].
8.2.6 PORT 1
If Port 1 is used as a bit programmable parallel I/O
port, it has the same features as a regular port.
When set as an Alternate Function, it is used as
the external memory interface to provide the ad-
dress bits A[15:8].

8.2.7 PORT 9 [7:2]
If Port 9 is available and used as a bit programma-
ble I/O port, it has the same features as a regular
port. If the MMU is available on the device and
Port 9 is set as an Alternate Function, Port 9[7:2] is
used as the external memory interface to provide
the 6 MSB of the address (A[21:16]).
Note: For the ST92F250 device, since A[18:17]
share the same pins as SDA1 and SCL1 of I²C_1,
these address bits are not available when the
I²C_1 is in use (when I2CCR.PE bit is set).
