If the temperature data is non-negative, the
binary data in CIO 2002 and CIO 2001 is
converted to BCD and placed in D101 and
D100.
(7)
If the temperature data is negative, the 2's
complement data in CIO 2002 and CIO
2001 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.
