(input)
For Memory Chip Selects, the Chip Select x Lower Bound register, listed in
page 56, defines the lower bound of the address range for which the corresponding Mem-
ory Chip Select, if enabled, can be active. For I/O Chip Selects, this register defines the
address to which ADDR[11:4] is compared to generate an I/O Chip Select. All Chip Select
lower bound registers reset to
