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.
