Reverse Initialization Response

This response message is sent during the next message

following a valid Reverse Initialization command to the

addressed device. The response is shown in Table 23. Since

this is a long-word only command, the short-word response is

invalid. No response is generated if the command address field

was $0.

Legend

A[3:0] = Address bits.The slave address.

BF = Bus Fault. BUSIN short to battery detected.

BS = Controls closing of the Bus Switch (1=close).

G[1:0] = Group bits. Not used on this part, will be set to “0”.

The group number programmed into the slave.

NV = Nonvolatile Memory Write. The value of the NV bit in the slave.

PA[3:0] = Bus Address to set the device to.

X[3:0] = Cyclic Redundancy Check (CRC). The CRC as calculated by

the slave.
