SRIX4K commands
9.4
32/50
SELECT(Chip_ID) command
Command Code = 0Eh
The SELECT() command allows the SRIX4K to enter the SELECTED state. Until this
command is issued, the SRIX4K will not accept any other command, except for INITIATE(),
PCALL16() and SLOT_MARKER(). The SELECT() command returns the 8 bits of the
Chip_ID value. An SRIX4K in SELECTED state, that receives a SELECT() command with a
Chip_ID that does not match its own is automatically switched to DESELECTED state.
