Details
Size:
2280 macro-cells and 1200 macro-cells
Type: [e.g., Flash PROM, EEPROM]:
Internal Flash EEPROM
Can user programs or operating system write
data to it during normal operation?
No
Does it retain data when powered off?
Yes
Purpose? [e.g., boot code]
System power sequence control, error/config
detection, and BIOS-BMC interaction.
How is data input to this memory?
Programming CPLD(s) requires a vendor
provided logic file and loader program which is
executed by booting up the system from a
floppy or OS based executable containing the
logic file and the loader. System loaded with
arbitrary data in CPLD(s) would not operate.
How is this memory write protected?
Software write protected
Remarks
Need AC cycle after updating CPLD
2 CPLD with 2280 on I/O board (CPLD1 – master)
& 1200 on CPU board (CPLD2 – slave)
