Altera Active Serial Memory Interface - Manual (Page 9)

Parameter Legal Values Descriptions
Use ‘sector_protect’ port —
• Enables the ability to protect sectors in the EPCS/
EPCQ/EPCQ-L device from write and erase operations
with an active-high input port named
sector_
protect
. When this port is asserted, the IP core reads
the block protection code value on the
datain[7..0]
signal and writes it to the EPCS/EPCQ/
EPCQ-L status register. To protect specific memory
sectors, you must send their block protection code to
the
datain[7..0]
signal.
• This option is available for all EPCS/EPCQ/EPCQ-L
devices.
Use ‘bulk_erase’ port —
• Enables the ability to erase the entire memory of the
EPCS/EPCQ/EPCQ-L256 device, including the
configuration data portion with an active-high input
signal named
bulk_erase
. When this signal is asserted,
the IP core implements a full erase that sets the entire
memory bits of the EPCS/EPCQ/EPCQ-L256 device to
a value of one.
• This option is available for all EPCS/EPCQ devices.
Use ‘sector_erase’ port —
• Enables the ability to erase a certain sector in the
EPCS/EPCQ memory with an active-high input signal
named
sector_erase
. When the signal is asserted, the
IP core implements a full erase of the sector. The value
of the
addr[23..0]
signal indicates the sector to erase.
For EPCQ256/EPCQ-L256 or larger devices, the width
of the
addr
and
read_address
signals is 32 bit.
• This option is available for all EPCS/EPCQ/EPCQ-L
devices.
Use ‘die_erase’ port —
• Enables the ability to erase each die in your device.
When the signal is asserted, the IP core implements a
full erase of a single die in your device. You need to
issue the erase die operation twice for EPCQ-L512
device and four times for the EPCQ-L1024.
• This option is available for Arria 10 devices with
EPCQL-512 and EPCQL-1024.
