Texas Instruments TMAG5328, User Manual, Page: 19 / 36

– This command allows you to configure the DAC output to create the same BOP that would be generated
by the input resistance. This is the same command executed by the GUI whenever you click the CHANGE
VALUE button while the "Modification Method" drop-down box is set to the "Manual R" option.
– VAL is the desired equivalent resistance value in units of Ω.
– VAL is in hex, and wreg is always lower case
– VAL can be in upper or lower case and does not need to be led by "0x". 0 padding VAL is also optional.
For example, to configure the DAC output to produce the same B
OP
that would be created if a 9000-Ω
resistor was connected to the ADJ pin instead of the DAC, some valid commands include:
• wreg 2 2328
• wreg 1 0x2328
– When "0x" is used, the "x" must be lower case.
– Figure 5-15 is an example response to this command

• Store to Nonvolatile Memory command: storenvm
– This command stores the current DAC output into nonvolatile memory. After power cycling the EVM,
the DAC output voltage will automatically be initiated to the value stored in nonvolatile memory, thereby
ensuring the same B
OP
value is used after power cycling the EVM. This is the same command executed
by the GUI whenever you click the STORE TO NVM button.
– Figure 5-16 is an example response to this command:

• Restore from Nonvolatile Memory command: reloadnvm
– This command sets the currently applied DAC output voltage to the voltage that is stored in nonvolatile
memory. This is the same command executed by the GUI whenever you click the RELOAD FROM NVM
button.

• Firmware revision command format: id
– This command prints the EVM the SCB is configured for (TMAG5328EVM in this case) and the date
associated with the version of the firmware loaded on the SCB.
