6.2.2 Set_Param (SAP61)

6.2.2.1 Parameter Data Structure

SPC3 evaluates the first seven data bytes (without user prm data), or the first eight data bytes (with user prm data). The first seven bytes are specified according to the standard. The eighth byte is used for SPC3- specific characteristics. The additional bytes are available to the application.

6.2.2.2 Parameter Data Processing Sequence

In the case of a positive validatation for more than seven data bytes, SPC3 carries out the following reaction, among others:

SPC3 exchanges Aux-Puffer1/2 (all data bytes are input here) for the Prm buffer, stores the input data length in ‘R_Len_Prm_Data’, and triggers the ‘New_rmP_Data Interrupt’. The user must then check the

‘User_Prm_Data’ and either reply with the ‘User_PrmData_Okay_Cmd’ or with ‘User_Prm_Data_Not_Okay_Cmd.’ The entire telegramis input in the buffer, that is, application-specific parameter data are stored beginning with data byte 8 only.

The user response (User_Prm_Data_Okay_Cmd or User_Prm_Data_Not_Okay_Cmd) again takes back the ‘New_Prm_Data’ interrupt. The user may not acknowledge the ‘New_Prm_Data’ interrupt in the IAR register.

The relevant diagnostics bits are set with the ‘User_Prm_Data_Not_Okay_Cmd’ message and are branched to ‘Wait_Prm.’

The ‘User_Prm_Data_Okay’ and ‘User_Prm_Data_Not_Okay’ acknowledgements are reading accesses to defined registers with the relevant signals:

∙ ‘User_Prm_Finished’:

No additional parameter telegram is present.

∙‘Prm_Conflict’ :An additional parameter telegramis present, processing again

∙ ‘Not_Allowed’,

Access not permitted in the current bus state
