(Step-1)
(Step-2)
Cancel the reset of the TMPM370 by setting the Single Boot mode pin to “0”, so that the CPU re-boots
from the on-chip boot ROM. The 12-byte password transferred from the host controller via SIO0 is first
compared to the contents of the special flash memory locations. (If the flash block has already been
erased, the password is 0xFFFF).
The flash block containing the older version of the program code need not be erased before executing
the programming routine. Since a programming routine and programming data are transferred via the
SIO (SIO0), the SIO0 must be connected to a host controller. Prepare a programming routine (a) on the
host controller.
