a. Mapped to fixed addresses in the SC140 core. Refer to the MSC8101 spec for complete description of the SC140’s Core internal memory map [4].

b. The device appears repeatedly in multiples of its port-size (in bytes) X depth. E.g., BCSR0 appears at memory locations 14700000, 14700010, 14700020..., while BCSR1 appears at 14700004, 14700014, 14700024... and so on.

c. The internal space of the ATM UNI control port is 256 bytes, however, the minimal block size that may be controlled by a CS region is 32KBytes. The same reason is for another peripherals.

d. Initially at hF0000000 - hF000FFFF, set by hard reset configuration.

e. Refer to the MSC8101 spec for complete description of the MSC8101’s Memory Map. f. Optionally.

Note: Address (except fixed) may moved about the map, to the convenience of any user.
