DSM2180F3V
A programmable security bit in the DSM protects
its contents from unauthorized viewing and copy-
ing. When set, the security bit will block access of
programming devices (JTAG or others) to the
DSM Flash memory and PLD configuration. The

only way to defeat the security bit is to erase the
entire DSM device, after which the device is blank
and may be used again. The DSP will always have
access to Flash memory contents through the 8-bit
data port even while the security bit is set.
