Read/Write NVM Response
This response message is sent during the next message
following a valid Read/Write NVM command to the addressed
device. The response format is found in
Table 17
. The high byte
is omitted during the short-word response. No response is
generated if the command address field was $0.
Clear Logic Out Command
The Clear Logic Out command sets the Logic Out pin to a
logic low. The compliment to this command is the Set Logic Out.
The Logic Out is also cleared at power-up or following a Clear
command. The format of the Clear Logic Out command is
shown in
Table 18
.
Clear Logic Out Response
This response message is sent during the next message
following a valid Clear Logic Out command to the addressed
device. The response is shown in
Table 19
. No response is
generated if the command address field was $0.
Set Logic Out Command
The Set Logic Out command sets the Logic Out pin to a logic
high. The compliment to this command is the Clear Logic Out.
The Logic Out is cleared at power-up or following a Clear
command. The format of the Clear Logic Out command is
shown in
Table 20
