Preliminary Technical Data
ADUC7032 KERNEL
The ADuC7032 features an on-chip Kernel resident in the top
2k of the Flash/EE Code space. After any reset event, this kernel
copies the factory calibrated data from the manufacturing data
space, into the various on-chip peripherals. The peripherals
calibrated by the Kernel are:
User MMRs which may be modified by the kernel and differ
from their POR default values are as follows:

The ADuC7032 also features an On-Chip LIN downloader. The
operation of this download is detailed in “ADuC7032Series
Flash/EE Programming via LIN” Technote.
A flow chart showing the execution of the kernel is shown in
Figure 13.
The current revision of the Kernel may be derived from
SYSSER1, as described in Table 85.
For the duration of Kernel execution, the Watchdog Timer is
active with a timeout period of 30ms. This ensures that if an
error occurs in the Kernel, the ADuC7032 will be reset. After
any reset, the Watchdog timer is disabled once the Kernel code
is exited.
Normal Kernel execution time, excluding LIN Download, is
approximately 5ms.
It is only possible to leave LIN download mode via a Reset.
SRAM is not corrupted during normal Kernel execution. SRAM
is corrupted during LIN download Kernel execution.
NOTE: User code will not be executed unless location 0x14
contains either 0x27011970 or the checksum of Page Zero,
excluding location 0x14. If location 0x14 does not contain this
information user code will not be executed and LIN download
mode will be entered. For more information please refer to the
relevant LIN download Technote.
