device. If an address is not defined for the device, then it can still be accessed by typing the subaddress

 

in the Address Edit box.

 

 

Data Edit Box

This contains the data which will be written to or was read from the I2C subaddress.

The data up/down arrows increment/decrement the data value by 1.

 

 

 

Write Button

Writes the byte in the Data Edit box to the address in the Address Edit box.

The I2C register is written to whether or not the data is different from the last time the register was read.

 

 

 

Read Button

Reads the data from the address in the Address Edit box into the Data Edit box and the register window.

 

 

Read All Button

Reads all defined readable registers from the device and updates the register window.

 

 

Hex Button

Converts all values in the register window and address and data edit boxes to hexadecimal.

 

 

Dec Button

Converts all values in the register window and address and data edit boxes to decimal.

 

 

 

Closes the dialog.

Close Button

NOTE: Multiple edit register map windows can be open at the same time (one for each device). Use the

 

Window menu to navigate.

 

 

Loop Count

Causes subsequent write, read or read all operations to be performed N times. N is entered as a

decimal number from 1 to 999.

 

 

 

8.3Property Sheets

The property sheets represent the register data in a user-friendly format. The data is organized by function, with each function having its own page and being selectable via tabs at the top.

To open this for the TVP5158, click on the following menu item: Edit > Property Sheets > TVP5158

When the property sheet function is started or whenever you tab to a different page, all readable registers in the device are read from hardware to initialize the dialog pages. Values on the page are changed by manipulating the various dialog controls as described in Table 11.
