123456
-- •
The CIF Unit receives 123456 from the
se
ri
al line.
• A parity error is detected.
2 • Input-
ting 12
• Discard-
ing 12
• The communications master
recei
ves the input notification data
given on the right.
• The communications master knows
that the
re is a parity error because
the Parity Error in the Port Status in
the input notification data is TRUE.
• The communications master dis-
cards 12.

• The CIF Unit inputs the following input noti-
fication data to pass 12 to the CPU Unit or
co
mmun
ications master.
• At the same time, the CIF Unit tells the CPU
U
n
it or communications master that there is
a parity error.
• The above input notification data is held
u
ntil the CPU Unit or communications mas-
ter sends output notification data in which
the
Inpu
t SID Response is 05 hex.

response
for 12
The communications master outputs
the fol
lowing output notification data to
tell the CIF Unit that 12 was received
normally.

• The CIF Unit receives the output notification
da
ta given on the left.
• The CIF Unit knows that 12 was normally
rece
ived by the CPU Unit or communica-
tions master because the Input SID
R
e
sponse in the output notification data is
05 hex.
