Command
Get Version Command
6071A–ATARM–28-Oct-04
A security bit can be set using the Set Security Bit command (SSE). Once the security bit is
active, the Fast Flash programming is disabled. No other command can be run. An event on
the Erase pin can erase the security bit once the contents of the Flash have been erased.
Table 31. Set Security Bit Command
The Get Version (GVE) command retrieves the version of the FFPI interface.
