4 REGISTER AND MEMORY MAP
4.1 INTRODUCTION
The ST92124-Auto/150-Auto/250-Auto register
map, memory map and peripheral options are doc-
umented in this section. Use this reference infor-
mation to supplement the functional descriptions
given elsewhere in this document.
4.2 MEMORY CONFIGURATION
The Program memory space of the ST92124-
Auto/150-Auto/250-Auto up to 256K bytes of di-
rectly addressable on-chip memory, is fully availa-
ble to the user.
4.2.1 Reset Vector Location
The user power on reset vector must be stored in
the first two physical bytes of memory, 000000h
and 000001h.
4.2.2 Location of Vector for External Watchdog
Refresh
If an external watchdog is used, it must be re-
freshed during TestFlash execution by a user writ-
ten routine. This routine has to be located in Flash
memory, the address where the routine starts has
68/430

to be written in 000006h (one word) while the seg-
ment where the routine is located has to be written
in 000009h (one byte).
This routine is called at least once every time that
the TestFlash executes an E
the write operation has a long duration, the user
routine is called with a rate fixed by location
000008h with an internal clock frequency of 2
MHz, location 000008h fixes the number of milli-
seconds to wait between two calls of the user rou-
tine.
Table 14. User Routine Parameters
If location 000006h to 000007h is virgin (FFFFh),
the user routine is not called.
