Memory Chip Select Priority
A lower-numbered Chip Select is given priority over a higher-numbered Chip Select. For
example, if the address space of Chip Select 0 overlaps the Chip Select 1 address space,
Chip Select 0 is active.
RESET States
On RESET, Chip Select 0 is active for all addresses, as its Lower Bound register resets to
00h
Upper Bound registers reset to
Memory Chip Select Example
The use of Memory Chip Selects is illustrated in
values are listed in
configured for memory addresses. Also, CS1 overlaps with CS0. As CS0 has the higher
than CS1, CS1 is not active for much of its defined address space.
CS0_LBR = CS1_LBR = 00h
and its Upper Bound register resets to
CS2_UBR = CFh
CS3_UBR = FFh
CS1_UBR = 9Fh
CS0_UBR = 7Fh
CS3_LBR = D0h
CS2_LBR = A0h
