On a Direct Read operation, if the CHIPID field matches the current device’s ID[4:0], this device will respond to the read request.
If the CHIPID field does not match, the device will not respond. Note that if the CHIPID does not match any device in the cascade,
no read acknowledge will be generated. If the CHIPID is set to broadcast (“11111”, binary), the device with the LDEV bit set to 1
will respond to the read request.
On an Indirect Read operation, if the CHIPID field matches the current device’s ID[4:0], this device will respond to the read
request. If the CHIPID field does not match, the device will not respond. Note that if the CHIPID does not match any device in
the cascade, no read acknowledge will be generated. If the CHIPID is set to broadcast (“11111”), each device examines its SSR
register’s VAL and GVAL bits. The device with one of these bits set responds to the read request. If none of these bits are set
(this occurs when a Search has not been done after a reset), no read acknowledge will be returned.
On a Direct Write operation, if the CHIPID field matches the current device’s ID[4:0], this device will perform the write request. If
the CHIPID field does not match, the device will not respond. If the CHIPID is set to broadcast, all devices write to the desired
location.
