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.

Legend
A[3:0] = Address bits. The slave address.
PA[3:0] = Programmed Address bits. The address that was
programmed into the NVM address bits of the slave.
X[3:0] = Cyclic Redundancy Check (CRC). The CRC as calculated by
the slave.
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.

BS = Bus Switch Position (1=closed).
LO = Logic out driven level.
IO[3:0] = Values at logic I/Os.
NV = Nonvolatile Memory Write. The value of the NV bit in the slave.
U = Undervoltage indicated true by a “1”.
X[3:0] = Cyclic Redundancy Check (CRC). The CRC as calculated by
the slave.
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.
