4.6.6
The Disable Self-Test Stimulus command may be transmitted as either a DSI long command structure or a DSI short command
structure of any length. The data field in the command structure is ignored but is included in the CRC calculation.
This command will execute if either the device specific address or DSI global device address (address $0) is provided. A
secondary function, self-test lockout, is activated when two consecutive Disable Self-Test Stimulus commands are received.
Following self-test lockout, the internal self-test circuitry is disabled until a Clear command is received or the device undergoes
power-on reset.
4.6.7
The Enable Self-Test Stimulus command may be transmitted as either a DSI long command structure or a DSI short command
structure of any length. The data field in the command structure is ignored but is included in the CRC calculation. No action is
taken by the device if this command is sent to the DSI Global Device Address.
