FUNCTIONAL DEVICE OPERATION
DSI COMMANDS AND RESPONSES
Reads and writes are long-word commands only. The
command format is found in Table 21.
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 22. 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 23.
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 24. No response is
generated if the command address field was $0.

A[3:0] = Address bits. These bits are the address of the device
previously sent with the Initialization command. They must match
the address in the PA[3:0] field and the address stored in the device
address register.
PA[3:0] = Program Address bits. These bits are the address that is to be
programmed into the slave.
X[3:0] = Cyclic Redundancy Check (CRC). The CRC as calculated by the
master.
