Description
Use the CC_DISPLAY_EHEX function to display an unsigned-integer
value in 4-digit hexadecimal on the ASCII display. The value must be in
the range of 0 through FFFF.
Important: ASCII display remains unchanged until another display
function call is performed successfully.
Be consistent when using hexadecimal or decimal radix on the ASCII
display for ease of interpretation—i.e., some hexadecimal values can
appear to be decimal values.
