have changed.

• Because this command is executed when data is mapped in the receive buffer, there may be
a delay between command receiving and status sending depending on the condition of the
receive buffer.

data input control command (ESC =), the 4 bytes of status is sent to the host whenever
status changes.

that command and the status due to ASB.
