4.4 The Register Map
The register map shows the entire user configurable register space for all programmable devices on the
CDB42L73.
It is especially useful for reading/writing a device’s register settings directly, one whole register at a time.
For example, the default value for register 0x11 is 0x15 (
Figure 15 ). To modify register 0x11’s value, first
navigate to it by locating the cell at the intersection of row “10” and column “01.” Click on the cell and simply
type the desired hexadecimal value for that register, then press the return key (Enter) on the keyboard.
To modify one bit of a register at a time, navigate to the desired register cell, click it, then click on the appli-
cable bits shown in the lower part of the register map page to toggle them.
Other useful controls:
• Reset All - clicking this button asserts reset to all devices on the CDB42L73
• Reset Device - clicking this button asserts reset to the device currently in view in the register map
• Released Reset - clicking this button holds/releases the device currently in view in the register map
in/from reset.
• Update Register - clicking this button refreshes the current selected register value
• Update Device - clicking this button refreshes all register values of the device currently in view in the
register map
