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.
