Character Code Setup Command
This command is used to specify the character to be displayed in the display location previously
specified by the Address Setup command. A built-in automatic address increment function
simplifies writing more than one display character code. All bytes transmitted after Byte 2 are
treated as character code data for successive locations. The internal address counter will be
automatically incremented from the address set using the Address Set command through
address 31 (or character 32), while executing valid write cycles, regardless of the number of digit
pairs as defined using the Number of Display Digits Setup command. In the event that additional
data is input to the MSC7170-01 following a valid write to address 31, the address counter will
wrap-around and continue to increment (to address 0 etc.) with write cycles disabled. This
prevents overwriting of the memory.

Display Duty Cycle Setup Command
This command is used to set the duty cycle of the display. The time allocated to a 1-digit display
is 1024T, where T is the period of the internal oscillator (f
OSC
). The display time for each digit may
be specified as 0 to 976T in increment of T. Entries greater than 976 default to 976. The display
duty cycle is calculated by dividing the input duty cycle value, DC, by 1024 times the number of
digits, n, commanded to display. Note that the percent duty cycle depends on how many digits
(characters) are displayed.
