ADuC7039
Normal kernel execution time, excluding LIN download, is less
than 5 ms. It is only possible to enter and leave LIN download
mode through a reset.
SRAM Address 0 to Address 0x2B are modified during normal
kernel execution, SRAM Address 0xFF to Address 0x110 are
also modified during a LIN download.
Note that even with NTRST = 0, user code is not executed
unless Address 0x1FC contains either 0x16400000 or the
checksum of Page 0, excluding Address 0x1FC. If Address

0x1FC does not contain this information, user code is not
executed and LIN download mode is entered. During kernel
execution, JTAG access is disabled.
The ADuC7039 is delivered with flash user space fully erased
and if NTRST = 0 at first power-up, the LIN download mode
is entered.
With NTRST = 1, user code is always executed and JTAG is
enabled.
