	Bit 0			MAC_Reset
				After it processes the current request, the SPC3 has arrived at the offline state (through
				setting the ‘Go_Offline bit’ or through a RAM acces violation).
	Bit 1			Go/Leave_DATA_EX
				The DP_SM has entered or exited the ‘DATA_EX’ state.
	Bit 2			Baudrate_Detect
				The SPC3 has exited the ‘Baud_Search state’ and oundf a baud rate.
	Bit 3			WD_DP_Control_Timeout
				The watchdog timer has run out in the ‘DP_Control’ WD state.
	Bit 4			User_Timer_Clock
				The time base for the User_Timer_Clocks has run out (1/10ms).
	Bit 5			Res
				For additional functions
	Bit 6			Res
				For additional functions
	Bit 7			Res
				For additional functions
	Bit 8			New_GC_Command
				The SPC3 has received a ‘Global_Control telegram’with a changed ‘GC_Command-
				Byte,’ and this byte is stored in the ‘R_GC_Command’ RAM cell.
	Bit 9			New_SSA_Data
				The SPC3 has received a ‘Set_Slave_Address telegram’ and made the data available
				in the SSA buffer.
	Bit 10			New_Cfg_Data
				The SPC3 has received a ‘Check_Cfg telegram’ andmade the data available in the Cfg
				buffer.
	Bit 11			New_Prm_Data
				The SPC3 has received a ‘Set_Param telegram’ andmade the data available in the
				Prm buffer.
	Bit 12			Diag_Puffer_Changed
				Due to the request made by ‘New_Diag_Cmd,’ SPC3 xchanged the diagnostics buffer
				and again made the old buffer available to the user.
	Bit 13			DX_OUT
				The SPC3 has received a ‘Write_Read_Data telegram’ and made the new output data
				available in the N buffer. For a ‘Power_On’ or fora ‘Leave_Master,’ the SPC3 deletes
				the N buffer and also generates this interrupt.
	Bit 14			Res
				For additional functions
	Bit 15			Res
				For additional functions
