10. UBC
When [User] is specified in the [UBC mode] list box in the [Configuration] dialog box, the
UBC can be used in the user program.
Do not use the UBC in the user program as it is used by the E10A emulator when [EML] is
specified in the [UBC mode] list box in the [Configuration] dialog box.
11. MFI Boot Mode
When the MFI boot mode is used, be sure to allocate the boot program from the top of
MFRAM.
12. 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, a Communication Timeout error will occur if the TLB
exception handler does not operate correctly. When [TLB miss exception is disable] is
selected, the program does not jump to the TLB exception handler even if a TLB exception
occurs. Therefore, if the TLB exception handler does not operate correctly, a Communication
Timeout error will not occur but the memory contents may not be correctly displayed.
13. 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 HS7729RKCI01H or HS7729RKCI02H is used: TCK = 4.125 MHz
•
When HS7729RKCM01H or HS7729RKCM02H is used: TCK = 3.75 MHz

Display and modification
Do not change values of the User Break Controller because it is used by the emulator.
For each watchdog timer register, there are two registers to be separately used for write and
read operations.
Table 2.3 Watchdog Timer Register
Register Name Usage Register
WTCSR(W) Write Watchdog timer control/status register
WTCNT(W) Write Watchdog timer counter
WTCSR(R) Read Watchdog timer control/status register
WTCNT(R) Read Watchdog timer counter
•
The watchdog timer operates only when the user program is executed. Do not change the
value of the frequency change register in the [IO] window or [Memory] window.
