When using two sets of 4 digits (n = K4 to K7)
→ For selection of "n", refer to Subsection 15.5.2.
1) Data and strobe signal
a) 1st set of 4 digits
A 4-digit numeric value stored in
is converted from binary into BCD, and its each digit is output in turn
from
to
+3 in the time division method.
The strobe signal is output in turn from
+4 to
+7 in the time division method also to latch the first
set of 4-digit seven-segment display unit.
b) 2nd set of 4 digits
A 4-digit numeric value stored in
+1 is converted from binary into BCD, and its each digit is output in
turn from
+10 to
+13 in the time division method.
The strobe signal is output in turn from
+4 to
+7 in the time division method also to latch the
second set of 4-digit seven-segment display unit. (The strobe signal outputs
+4 to
+7 are shared
by the 1st and 2nd sets.)
2) For
and
+1, binary data in the range from 0 to 9999 is valid.
