1.4 USB and RTC Modules of the H8S/2218, H8S/2212
· Access Area
The USB and RTC modules are allocated to the external bus area of area 6 (H'C00000 to H'DFFFFF) and
area 7 .(H'E00000 to H'FFFFFF), respectively.
Therefore, the access area that has been traced for this area is displayed in the external area (EXT-8).
There is no display of 'Internal IO' for areas H'C00000 to H'DFFFFF by the [Target Device Configuration]
item in the [Memory] sheet of the [Status] window.
1.5 Voltage Follower Circuit
When setting the Vccdown detection voltage in the voltage follower circuit, make the setting be at least
2.6 V or higher.
1.6 Reserved Area to be Changed for External Address Area
The reserved area that can be changed for the external address area by clearing the RAME bit in the
system control register (SYSCR) to 0 is used as the external address area, change the attribute of this area
from 'User Guarded' to 'User Read-write' or 'User Read-only' in the [Memory Mapping] dialog box that is
displayed by selecting [Emulator -> Memory Resource...] from the [Setup] menu, before loading the user
program.
However, if other attributes than 'User Guarded' are set, an accessing-error break for this area will not
occur.
Be careful when the reserved area (RAME = 1) is also used as the external address area (RAME = 0).
1.7 Event
1.7.1 Combination of Address-Range and Data Compare-Byte
When an address range is set as the address condition and byte data as the data condition, a break will
occur only at even addresses in the address range. When an address range is set as the address condition,
do not set an odd address as the Address Lo condition. Otherwise, a break will not occur even when the
conditions are satisfied.
1.7.2 Removing Software Breakpoints during Execution of the User Program
Do not remove Software breakpoints in the source window, [Disassembly] window, or [Label] window
during execution of the user program.
1.7.3 Recovery of Software Breakpoints by the Session File
Information on Software breakpoints that was saved in the session file is not available until a load
module is loaded. If necessary, load a load module or set new Software breakpoints.
1.8 Display of the Memory Content and Operation of Memory
1.8.1 Operating Memory during Execution of the User Program
The memory copy, memory compare, memory fill, and memory test functions are not available during
execution of the user program. These command lines are not available either.
