Contents
Data request input signal
(1bit)
When this signal is turned on, input settings at
the termial, such as Frame number, Comparator
group number, Output mode…etc. will be
reflected to the output of the I/O terminal.
Target frame number
(4bits)
Select Frame number using 4bits.
※Target frame number =A to P
(The 4 bits to be set are 0000b to 1111b)
Comparator group number
(3bits)
Select “Comparator group number” using 3bits,
for the target frame number specified above.
※Comparator group number =1 to 8
(The 3 bits to be set are 000b to 111b)
Output mode
(2bits)
Select the “Output mode” using 2bits, for the
target frame specified above.
※Output mode
00b:Current value
01b:Maximum value
10b:Minimum value
11b:Peak to peak value

Comparator area information
output
(5bits)
When the Data ready signal becomes Low level
(On), the output terminal assigned for this
function will output comparator area.
