3.2.3

Register Online Adjust Area

The “Register Online Adjust” section of the GUI allows the user to have direct control 
of register values at any time when operating the MCP19117. The device data sheet 
contains information on register address locations and content. Reads and writes are 
done in hexadecimal format. Users must select the proper bank, which is especially 
important when executing a write. It is good practice to always execute an address read 
before a write, to check for expected results. This may help prevent an unintended write 
to an improper address or bank. Please note that the 

Update

 button will not update this 

section.

In this section the user can perform the following actions:
• Click the 

Initialize PICkit Serial

 button for the system to check the communica-

tion between your computer and PICkit Serial Analyzer. 

• Click the 

Check for Evaluation Board

 to manually ask the system to detect the 

evaluation board.

• Click the 

Update

 

button to apply the configuration settings made in “Operating 

Mode”, “Parameters”, “Protection”, “Switches Enable/Disable”, and “Advanced 
Register Update” areas. Clicking 

Update

 also turns on the output drivers. Note 

that it does not update information in the Register Online Adjust area.

• The 

Turn Off Drivers

 button is a master stop that shuts off the output drivers. 

Clicking this button disables both primary and secondary drivers. 

The system communicates whether the user action was successful or not in the Oper-
ating Status Box (see

 Figure 3-10

).
