This section provides a detailed description of address space and registers used by the XGATE module.
The memory map for the XGATE module is given below in
.The address listed for each register
is the sum of a base address and an address offset. The base address is defined at the SoC level and the
address offset is defined at the module level. Reserved registers read zero. Write accesses to the reserved
registers have no effect.
