Bus operations are defined in Table 3.
Following the Intelligent Identifier command, two read operations access manufacturer and device codes. A
0
= 0 for
manufacturer code, A
0
= 1 for device code. A
1
—A
21
= 0.
Either 40H or 10H command is valid although the standard is 40H.
When writing commands to the device, the upper data bus [DQ
8
–DQ
15
] should be either V
IL
or V
IH
, to minimize current
draw.
