4.2 Processor Parameters (Latches/Register)

These cells can be either read only or written only. SPC3 carries out “address swapping” for an access to the address area 00H - 07H (word register) in the Motorola mode. That is, the SPC3 exchanges

address bit 0 (generated from an even address, one uneven, and vice-versa). The following sections more clearly explain the significance of the individual registers.

Address			Name	Bit	Significance (Read Access!)
Intel	/ Motorla		No.

00H		01H	Int-Req-Reg		Interrupt Controller Register
			7..0
01H		00H	Int-Req-Reg
			15..8
02H		03H	Int—Reg
			7..0
03H		02H	Int—Reg
			15..8
04H		05H	Status-Reg		Status Register
			7..0
05H		04H	Status-Reg
			15..8
06H		07H	Reserved
07H		06H
	08H		DIN_Buffer_SM		Buffer assignment of the
			7..0		DP_Din_Buffer_State_Machine
	09H		New_DIN_Buffer_Cmd		The user makes a new DP Din buffer available in
			1..0		the N state.
0AH			DOUT_Buffer_SM		Buffer assignment of the
			7..0		DP_Dout_Puffer_State_Machine
0BH			Next_DOUT_Buffer_Cmd		The user fetches the last DP Dout-Buffer from the N
			1..0		state.
0CH			DIAG_Buffer_SM		Buffer assignment for the
			3..0		DP_Diag_Puffer_State_Machine
0DH			New_DIAG_Puffer_Cmd		The user makes a new DP Diag Buffer available to
			1..0		the SPC3.
0EH			User_Prm_Data_OK		The user positively acknowledges the user
			1..0		parameter setting data of a Set_Param-Telegram.
	0FH		UserPrmDataNOK		The user negatively acknowledges the user
			1..0		parameter setting data of a Set_Param-Telegram.
	10H		User_Cfg_Data_OK		The user positively acknowledges the configuration
			1..0		data of a Check_Config-Telegram.
	11H		User_Cfg_Data_NOK	1..0	The user negatively acknowledges the configuration
					data of a Check_Config-Telegram.
	12H		Reserved
	13H
	14H		SSA_Bufferfreecmd		The user has fetched the data from the SSA buffer
					and enables the buffer again.
	15H		Reserved
