Table 6.1
On the other hand, this memory is located in a part of area 1 in the physical address space. When
this memory is accessed from the physical address space, addresses in which the upper three bits
are 0 in addresses shown in table 6.1 are used. In the X-bus and Y-bus address spaces, addresses in
which the upper 16 bits are ignored in addresses of X memory and Y memory shown in table 6.1
are used.

There are four pages. The X memory is divided into two pages (pages 0 and 1) and the Y
memory is divided into two pages (pages 0 and 1).
The X/Y memory is located in the virtual address space, physical address space, and X-bus and
Y-bus address spaces.
In the virtual address space, this memory is located in the addresses shown in table 6.1. These
addresses are included in space P2 (when SR.MD = 1) or Uxy (when SR.MD = 0 and SR.DSP
= 1) according to the CPU operating mode.
Each page has three independent read/write ports and is connected to each bus. The X memory
is connected to the I bus, X bus, and L bus. The Y memory is connected to the I bus, Y bus,
and L bus. The L bus is used when this memory is accessed from the virtual address space.
The I bus is used when this memory is accessed from the physical address space. The X bus
and Y bus are used when this memory is accessed from the X-bus and Y-bus address spaces.
