SECURITY BIT
A programmable security bit is provided on the MACH 5 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.
