The Error Recovery Control command can be used to set time limits for read and write error recovery. For non-
queued commands, these timers apply to command completion at the host interface. For queued commands where
in order data delivery is enabled, these timers begin counting when the device begins to execute the command, not
when the command is sent to the device. These timers do not apply to streaming commands, or to queued commands
when out-of-order data delivery is enabled.
These command timers are volatile. The default value is 0 (i.e. disable command time-out).
