Entering c from the Change Mode Menu allows the user
to customize the operational parameters of the HI7190.
The user will be asked a series of questions relating to
HI7190 operation. After completing these questions, the
software compiles the proper data and writes the Control
Register to invoke the desired operating mode. Execut-
ing this command returns the user to the Main Menu.
