Request Status Response
This response message is sent during the next message
following a valid Request Status command to the addressed
device. The response format is found in
Table 7
. The high byte
is omitted during the short-word response. No response is
generated if the command address field was $0.
Request Value n Command
This command will cause the analog level at one of the four
I/O lines to be measured and returned on the following
command. The command format is found in
Table 8
. The
analog input measured is defined in
Table 9
.
Request Values Response
This response is an 8-bit value representing the value
measured by the ADC. The selection of “n” is a function of the
command. This is shown in
Table 10
.
The read will be completed during the idle period and will
represent the voltage at the end of the command. If an
undervoltage condition exists at any time during the command
or the measurement has not completed properly, a value of
“00000000” will be returned. This is a reserved value to indicate
a problem with the measurement. The minimum valid level
reported will be “00000001”. No response is generated if the
command address field was $0.
