SELECT(Chip_ID)
Command Code = 0Eh,(X.ID)h
Prior to any memory access, the SR176 must have been set in the SELECTED state by a
SELECT() command. All other commands sent to the SR176 before the SELECT(), except
INITIATE(), are ignored. In response to receiving the SELECT() command, the SR176
sends back its Chip_ID, using an 8-bit format
Any SR176 that is already in the SELECTED state, and which receives a SELECT()
command that does not match its Chip_ID, is automatically put in the DESELECTED state.
The SR176 stays in the SELECTED state up to the reception of a COMPLETION or a
SELECT with a non-matching Chip_ID.
After a PROTECT_BLOCK command, it is necessary to send a new SELECT command in
order to load enable the write access again in the internal logic. If a SELECT is not send, the
SR176 keeps the previous write access rights.
