COM1 - 4 = common backplane signals
S1_n, S2_n = segment signals
n = 0 is most right digit, n= 11 is most left digit for 12-digit displays,
and n = 15 is most left digit for 16-digit displays.

The symbols in
bold
are always enabled and other symbols can be enabled through the serial interface. Symbols
will be displayed independently from selecting the upper bank of the 32 digit buffer to be displayed.
The AS2591 incorporates a buffer for 32 digits. Digits are entered from the most right position and shifted left by
new entries (see also Table 2: Commands).
