MAD[31] NVSRAM or SRAM Installed – Pulling this signal HIGH
indicates that an NVSRAM or an SRAM is installed. Pulling this signal
LOW indicates that neither an NVSRAM nor an SRAM is installed.
MAD[30] NVSRAM or SRAM Select – Pulling this signal LOW when
MAD[31] is pulled HIGH indicates that an SRAM is installed. Pulling
this signal HIGH when MAD[31] is pulled HIGH indicates that an
NVSRAM is installed.
MAD[29] SGPIO CPLD Installed – Pulling this signal LOW indicates
that an SGPIO CPLD is not installed. Pulling this signal HIGH
indicates that an SGPIO CPLD is installed.
