SECURITY BIT
A security bit is provided on the MACH devices as a deterrent to unauthorized copying of the array
configuration patterns. Once programmed, this bit defeats readback of the programmed pattern by
a device programmer, securing proprietary designs from competitors. Programming and
verification are also defeated by the security bit. The bit can only be reset by erasing the entire
device.
