Figure 7. LP8866EVM Diagnostics Page
2.6.3 Register Map Page
Figure 8 shows the registers map page. All the registers are available on this page. When "Auto Read" is
set to other than "Off", all the registers will be read automatically and periodically according to the interval
time the user selects. Otherwise the user will need to click "READ REGISTER" to read the selected
register or to click "READ ALL REGISTERS" to read all registers.
Clicking on the row of a register automatically updates the corresponding field view on the right side of the
page. The register value can be updated by modifying the hexadecimal value in the "Value" column or by
double-clicking the corresponding bit in the "Bits" column. The modified value is effective immediately if
"Immediate Write" is selected. When "Deferred Write" is selected, the modified value won't take effect until
the user clicks "WRITE REGISTER" button. All registers' value can be updated together by clicking
"WRITE ALL REGISTERS".
