−I/O is at x'0d00_0000 (Starlet private) and x'0d80_0000 (shared with the Broadway).
+I/O is at x'0d80_0000 (Starlet private) and x'0d00_0000 (shared with the Broadway). That is to say, the contents of 0x0d8x are selectively mirrored to 0x0d0x. This may change depending on some of the registers (e.g. when MIOS is active).
There is internal SRAM at x'fffe_0000, 128kB of it; this stores the kernel code and data, minus the crypto code.
