Description

Required

Type

Parameter Name

Specifies the access mode for the user flash
memory. Values are READ_WRITE and READ_
ONLY. This parameter is used with the parallel or
SPI interface protocol only.

No

String

ACCESS_MODE

Specifies the configuration mode for the SPI
interface protocol. Values are BASE and
EXTENDED. The default is EXTENDED. When
the CONFIG_MODE parameter is set to
EXTENDED, the flash memory uses 16-bit word
size for the address and data word. When the
CONFIG_MODE parameter is set to BASE, the
flash memory uses 8-bit word size for the address
and data word and uses only sector 0 of the UFM.

When the CONFIG_MODE parameter is specified
to BASE and you specify a MIF or HEX file, you
must specify the initial contents of sector 0 and 1
of the UFM. Addresses 0 through 255 of the MIF
or HEX file must contain user data while addresses
256 through 511 should be set to 1. If you use a
HEX file, you must specify all 16-bits of data. The
user data (8-bits) should be placed in the MSBs of
the data word and the LSBs should be padded with
1.

Yes

String

CONFIG_MODE

Name of the Memory Initialization File (.mif) or
Hexadecimal (Intel-Format) Files (.hex) containing
RAM initialization data (<file name>), or
UNUSED.

No
