SELECT(Chip_ID) Command
Command Code = 0Eh
The SELECT() command allows the SRI4K to en-
ter the SELECTED state. Until this command is is-
sued, the SRI4K will not accept any other
command, except for INITIATE(), PCALL16() and

SLOT_MARKER(). The SELECT() command re-
turns the 8 bits of the Chip_ID value. An SRI4K in
SELECTED state, that receives a SELECT() com-
mand with a Chip_ID that does not match its own
is automatically switched to DESELECTED state.
