Access kind
The Access Kind list menu provides a way to indicate that the memory range is read/write
(R/W), read only, write only or none of these.
When defined as read only, the range is never written by the debugger.
When defined as write only, the range is never read by the debugger.
When defined as none, the range is never read or written by the debugger. This is internal
equivalent as not defining the range in the DMM dialog.
Access Size
When available, the Access Size list menu provides a way to define if the memory range is
accessed as byte (1), short (2) or long (4).
NOTE The memory range must be size aligned. For example, a module defined with
access size 2 must start with an even address and finish on an odd address. A
module defined with access size 4 must start with an address with the least
significant byte in 0, 4, 8, C, and finish with an address with the least
significant byte in 3, 7, B, F.
NOTE A memory range overlapping (in priority) another memory range can only have
the same or a higher access size.
Types
The Type list menu provides all kinds of memory types available for the processor
displayed in the title bar of the dialog. For some connections, the CPU core might be
displayed instead of the processor name.
Types are internal rules to read and write a kind of memory. For examples, the HCS08
banked type requires first setting a register called PPAGE to read the memory, then
restoring this value as it was before reading. Also this banked type does not physically
provide a memory access while running. Memory access while running is possible in
physical memory (RAM, registers).
