• MFI Boot Mode
When the MFI boot mode is used, be sure to allocate the boot program from the top of MFRAM.
• Using RWDT
At power-on reset, the operation of RWDT is enabled. When RWDT is not used, be sure to
disable the operation of RWDT at the top of the user-reset program.
• Memory Access during Break
In the enabled MMU, when a memory is accessed and a TLB error occurs during break, it can be
selected whether the TLB exception is controlled or the program jumps to the user exception
handler in [TLB Mode] in the [Configuration] dialog box. When [TLB miss exception is enable]
is selected, the program jumps to the TLB exception handler. If the TLB exception handler does
not operate correctly, a message is displayed to inform that a TLB error has occurred. When [TLB
miss exception is disable] is selected, the program does not jump to the TLB exception handler
even if a TLB error occurs.
• Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be as follows:
When HS7290KCI01H or HS7290KCI02H is used: TCK = 1.031 MHz
When HS7290KCM01H or HS7290KCM02H is used: TCK = 0.937 MHz
• Registers Related to DSP
DSP bit in the SR register and any registers related to DSP cannot be changed from the [Register]
window. To do so, change them in the user program.
DSP bit in the SR register and any registers related to DSP also cannot be recovered by loading
sessions.
• Session Files
There are three kinds of session files: HDI session files (*.hds), target session files (*.hdt), and
watch session files (*.hdw). For details on HDI session files and watch session files, refer to the
Hitachi Debugging Interface User’s Manual attached with the CD-R. The following information
will be saved as target session file information of the emulator:
[Break point] dialog box
[Break Condition] dialog box
[Trace Acquisition] dialog box
[Configuration] dialog box (except for Jtag Clock)
[Performance 1] dialog box
