ZEROIZE
For security, the board provides a digitial zeroize input. This section describes the available zeroization
parameters. For more information on the signal, refer to "Zeroization" in Chapter 3.
optzdelay
Sets the debounce time (the minimum amount of time the zeroize input must be asserted before the
zeroize feature is invoked).
Syntax
Debug Parvus OptZDelay <integer>
<integer> is 2-255, where 2=200 mS, 255=25.5 seconds. The default is 20 (2.0 seconds).
Example
SWI2210-XXXX:/Debug/Parvus>optzdelay 50
optzenable
Enable/disable zeroize feature. Zeroize must be enabled before it can be invoked.
Syntax
Debug Parvus OptZEnable <integer>
<integer> is 0 (disable) or 1 (enable). Default is 0.
Example
SWI2210-XXXX:/Debug/Parvus>optzenable 0
optzpolarity (do not use)
Sets the polarity of the zeroize input.
Syntax
optzpolarity <integer>
<integer> is 0 (12 VDC) or 1 (grounded). Default is 0.
Example
SWI2210-XXXX:/Debug/Parvus>optzpolarity 0
optzstyle (do not use)
Sets the zeroize style (what is erased by the zeroize input). The 3 levels are:
 Erase only configuration options and data; reboot the board.
 Erase the application firmware and configuration options and data.
 Erase the bootloader, application firmware, and configuration options and data.
Syntax
Debug Parvus OptZStyle <integer>
<integer> is
0 (configuration only),
1 (configuration and -Config/app,
2-Config/app/bootloader.
Example
SWI2210-XXXX:/Debug/Parvus>optzstyle 0
