Figure 4. Direct Register access
Binary data may be written and read from the registers. Use hexadecimal values in address and data
fields. Individual bits for the register set in 'Address' are shown with a brief description of their function in
this dialog window. The Correct data value can also be created by setting and clearing these individual bit
check boxes. The value is immediately written to the device by pressing ‘Write’ button and the register
setting may be read from the device by pressing ‘Read’ button.

Control
A green LED (PWR_OK) will be illuminated once the LM10507EVM has power applied and the device is
enabled. JP11 and J13 should be set accordingly.
The logic signals can be controlled either by the evaluation software or externally through connector
labeled ‘I/O LINE SEL’. Set the jumper block from JP2 to JP9 accordingly.
