Am79C930
Some of the Am79C930 device’s PCMCIA Common
Memory locations have predefined uses and, therefore,
are not freely available to the device driver. The
following

Am79C930 device:

SIR1[5:3]
Restricted Space
0000h – 03FFh
000
1 Kbytes
SRAM Memory 0 0000h – 0 03FFh
This space is reserved for the interrupt
vector table of the embedded 80188
core.
0400h – 041Fh
000
32 bytes
SRAM Memory 0 0400h – 0 041Fh
This SRAM space is inaccessible to
the 80188 embedded core, since the
80188 core maps the 32 TIR registers
of the TAI into this portion of 80188
memory space.
0420h – 043Fh
000
32 bytes
SRAM Memory 0 0420h – 0 042Fh
This SRAM space is inaccessible to
the 80188 embedded core, since the
80188 core maps the MIR registers of
the BIU (PIR, PDLC and PUCT) and
XCE space into this portion of 80188
memory space.
0440h – 047Fh
000
64 bytes
SRAM Memory 0 0440h – 0 047Fh
This SRAM space is reserved for future
use and may be decoded for non-
SRAM purposes in the future.
7C00h – 7FEFh
111
1K–16 bytes
Flash Memory 1 FC00h – 1 FFEFh
These bytes of the Flash memory also
map into PCMCIA Attribute Memory
space 0000h – 03FFh, which is used
for storing the CIS for the device.
Therefore, this space cannot be used
for non-CIS purposes.
7FF0h – 7FFFh
111
16 bytes
Flash Memory 1 FFF0h – 1 FFFFh
These 16 bytes of Flash memory
space are reserved because they are
the location of the embedded 80188
core’s instruction pointer following a
Am79C930 device reset operation.
These 16 bytes must contain the first
80188 instructions.
