NVRAM COMMANDS
The monitor uses the I
2
C EEPROM for nonvolatile memory. A memory map of the I
2
C
EEPROM is given in
Tab le 4 -2 earlier in this manual. Portions of this nonvolatile memory are
reserved for factory configuration and identification information and the monitor.
The nonvolatile memory support commands provide the interface to the I
2
C EEPROM. The
nonvolatile commands deal only with the monitor- and Emerson-defined sections of the
nonvolatile memory. The monitor-defined sections of nonvolatile memory are readable
and writeable and can be modified by the monitor.
nvdisplay
is used to display the Emerson-defined and monitor-defined nonvolatile sections. The non-
volatile memory configuration information is used to completely configure the PmT1 and
PmE1 modules at reset. The utility command configboard can also be used to reconfigure
the board after modifications to the nonvolatile memory.
Description:
nvdisplay
The configuration values are displayed in groups. Each group has a number of fields. Each
field is displayed as a hexadecimal or decimal number, or as a list of legal values.
To display the next group, press <space> or <cr>.
To edit fields within the displayed group, press E.
To quit the display, press <ESC> or Q.
To save the changes, type the command nvupdate.
To quit without saving the changes, type the command nvopen.
Tab le 8 -1 shows all the groups and fields you can edit when you use the nvdisplay command.
Example:
1 At the monitor prompt, type:
=>nvdisplay
2 Press <cr> until the group you want to modify is displayed. An example for the group
“Console” is shown below.
