The SET FEATURES (EFh) and GET FEATURES (EEh) commands are used to modify the
target's default power-on behavior. These commands use a one-byte feature address to
determine which subfeature parameters will be read or modified. Each feature address
(in the 00h to FFh range) is defined in below. The SET FEATURES (EFh) command
writes subfeature parameters (P1–P4) to the specified feature address. The GET FEA-
TURES command reads the subfeature parameters (P1–P4) at the specified feature
address.
When a feature is set, by default it remains active until the device is power cycled. It is
volatile. Unless otherwise specified in the features table, once a device is set it remains
set, even if a RESET (FFh) command is issued. GET/SET FEATURES commands can be
used after required RESET to enable features before system BOOT ROM process.
Internal ECC can be enabled/disabled using SET FEATURES (EFh). The SET FEATURES
command (EFh), followed by address 90h, followed by four data bytes (only the first
data byte is used) will enable/disable internal ECC.
The sequence to enable internal ECC with SET FEATURES is EFh(cmd)-90h(addr)-
08h(data)-00h(data)-00h(data)-00h(data)-wait(
The sequence to disable internal ECC with SET FEATURES is EFh(cmd)-90h(addr)-
00h(data)-00h(data)-00h(data)-00h(data)-wait(
is EEh.
