If the temperature data is non-negative, the
binary data in CIO 202 and CIO 201 is
converted to BCD and placed in D101 and
D100.
(7)
If the temperature data is negative, the 2's
complement data in CIO 202 and CIO 201 is
converted to binary data representing the
absolute value of the temperature input and
placed in H1 and H0.

(8)
The binary data in H1 and H0 is
converted to BCD and placed in D101
and D100.
(9)
"1" is written to the bit in D101 indicating
negative data.
