Bit 3
IP-D Memory Enable
(Read/Write)
Writing a "1" to this bit enables the memory space for IP D. A zero disables
memory space accesses.
Reset Condition: Set to "0", memory space accesses disabled for IP D.
Bit 2
IP-C Memory Enable
(Read/Write)
Writing a "1" to this bit enables the memory space for IP C. A zero disables
memory space accesses.
Reset Condition: Set to "0", memory space accesses disabled for IP C.
Bit 1
IP-B Memory Enable
(Read/Write)
Writing a "1" to this bit enables the memory space for IP B. A zero disables
memory space accesses.
Reset Condition: Set to "0", memory space accesses disabled for IP B.
Bit 0
IP-A Memory Enable
(Read/Write)
Writing a "1" to this bit enables the memory space for IP A. A zero disables
memory space accesses.
Reset Condition: Set to "0", memory space accesses disabled for IP A.
3.6 IP Memory Base Address & Size Register (Read/Write)
IP_A (Base + D1H), IP_B (Base + D3H), IP_C (Base + D5H), IP_D (Base + D7H),
The IP Memory Base Address & Size Registers are user programmable to
define the starting address of standard (A24) memory space and the size of
that memory space corresponding to IP modules A through D. The memory
size for each enabled IP module is user-programmable from 1MByte to
8MByte in multiples of two. Note that memory on IP modules can only be
accessed if enabled within the IP Memory Enable Register, and that the
memory bases for enabled IP modules must not be programmed to overlap
with each other. The size selected by these registers should be matched to
that required by the associated IP.
