Legal values for wValue are as follows:
0x0000 Internal Config bytes, address range 0x2 – 0xF
0x0002 External I
2
C memory device
Internal Config byte writes must be constrained to addresses 0x2 through 0xF, as shown in
Table 12
. Attempts to write outside
this address space result in undefined operation. Internal Config byte writes only overwrite AT2LP Configuration Byte registers,
the original data source (I
2
C memory device) remains unchanged.
READ_CONFIG_DATA
This USB request allows data retrieval from the data source specified by the wValue field. Data is retrieved beginning at the
address specified by the wIndex field (see
Table 12
). The wLength field denotes the length in bytes of data requested from the
data source.
Legal values for wValue are as follows:
0x0000
Configuration bytes, addresses 0x0 – 0xF only
0x0002
External I
2
C memory device
Illegal values for wValue result in an undefined operation. Attempted reads from an I
2
C memory device when none is connected
result in an undefined operation. Attempts to read configuration bytes with starting addresses greater than 0xF also, result in an
undefined operation.
