5.7.3
TARGETED RESET
The Targeted Reset command provides a mechanism for the Master to cause a re-initialization of a specific slave device on the network, designated by the NAD in the command. Upon receipt of the Targeted Reset command, the slave device shall cause an internal reset of operational variables to occur. Examples of operational variables include, but are not limited to, program counters, mode control variables, communications error counters, input source re-initializations, and output device reinitializations, but shall not alter any previously configured application level configuration information stored in non-volatile memory. This Reset operation shall not cause the slave to destructively alter any LIN configuration data or addresses stored in non-volatile memory. Also, the Reset operation shall not cause any configuration parameters in the LIN Data Link device (UART) to be altered. Upon conclusion of the Reset operation, the slave device shall remain configured, and shall assume a state consistent wit
h a power-on initialization, with the exception of the LIN configuration information. The slave shall also retain knowledge that it has undergone a reset operation, such that a positive response can be provided to the Master. The LIN Slave device shall be able to respond to a$3D request frame which starts immediately after the stop bit of the checksum byte of the$3C Targeted Reset command frame. For those devices that are always in the power-on state, i.e. input only devices, a Reset Command may have no impact on the device state; however, this device shall still set the reset flag within the J2602 status byte and shall send a positive response. A device may elect not to perform the requested Reset command based on the application program requirements. In this case, the device will respond with a Negative Response. 5.7.3.1Tx by Master LIN ID$3C
