Overlay Character Generator

Character Generator Details

Table 21 shows the characters that can be generated.

It is the responsibility of the user to set up proper values in the character positioning to

fit them in the same row (that is one of the reasons that 22 is the maximum number of

characters).

Note:

No error is generated if the character row overruns the horizontal or vertical limits of

the frame.
