[REG]: Register Map This tab is for a register writing and reading. Each bit on the register map is a push-button switch. Button Down indicates “H” or “1” and the bit name is in red (when read only it is in deep red). Button Up indicates “L” or “0” and the bit name is in blue (when read only it is in gray) Grayout registers are Read Only registers. They can not be controlled. The registers which is not defined in the datasheet are indicated as “---”. <KM101302> 2010/08 -9- ASAHI KASEI [AKD4223-A] [Write]: Data Writing Dialog It is for when changing two or more bits on the same address at the same time. Click [Write] button located on the right of the each corresponded address for a pop-up dialog box. When checking the checkbox, the register will be “H” or “1”, when not checking the register will be “L” or ”0”. Click [OK] to write setting value to the registers, or click [Cancel] to cancel this setting. [Read]: Data Read Click [Read] button located on the right of the each corresponded address to execute register reading. After register reading, the display will be updated regarding to the register status. Button Down indicates “H” or “1” and the bit name is in red (when read only it is in deep red). Button Up indicates “L” or “0” and the bit name is in blue (when read only it is in gray) Please be aware that button statuses will be changed by Read command. <KM101302> 2010/08 - 10 - ASAHI KASEI [AKD4223-A] ■ Dialog Boxes 1. [All Reg Write]: All Reg Write dialog box Click [All Reg Write] button in the main window to open register setting files. Register setting files saved by [SAVE] button can be applied.
