Register Map
Table 7 shows the CircLink register map. All registers are 16 bits wide and can be word-accessed and
byte-accessed in 16-bit mode (W16 = H) and 8-bit mode (W16 = L) respectively. In the case of byte
access, the lower byte (bits 7 to 0) is assigned to an even address and the upper byte (bits 15 to 8) to an
odd address by default. This assignment can be reversed by setting the nSWAP pin to L.
Adr. : CPU Address A[5:0] in Hex value. (Address 00h to 0Fh are registers specific to ARCNET)
- Word access (W16=High)
- Byte access and No Swap (W16=Low, nSWAP=High)
