Renesas SDI Emulator System M32100T-EZ-E - Manual (Page 12)

Note on Specifying Breakpoints:
• Due to the MCU's architecture, the following addresses cannot be set as a breakpoint.
(1) Addresses (4n + 2) in the middle of a 1-word instruction
(2) Addresses (4n + 2) in an instruction located in word align + 2 addresses, which are executed
in parallel
Notes on Reset Control Switch:
• It is always recommended to set this switch to LOW.
• When the reset control switch on the emulator is set to Hiz START, the following operation allows
you to execute the program from the reset vector during time from (2) to (3).
(1) Turn on the emulator.
(2) Turn on the target system.
(3) Start the emulator debugger PD32RM.
This phenomenon occurs immediately after the emulator starts up only.
Note on Using Reset Mask:
• If the reset signal from the target board is masked (disabled) using the script command (ResetMask)
of the emulator debugger, the reset signal that is input to the target MCU during target program
execution will be ignored and the target MCU will not be reset.
By resetting only peripheral circuits, problems will occur such as target MCU bus cycles not
completing, and the target MCU may runaway.
IMPORTANT
Note on Target Program Execution in Real-time:
• The DMA controller for the emulator incorporated in the MCU is used for the memory references/
settings during target program execution. Therefore, for the memory references/settings during
target program execution, the bus-cycle by the DMA controller occurs.
Note on Access Prohibited Areas:
• The emulator uses the addresses H'FFFF 8000 to H'FFFF 9FFF of the target MCU as the dedicated
area for the emulator. When accessing to this area from the target program, the operation of the
emulator cannot be guaranteed. Therefore, do not access to this area from the target program.
Note on LED Display:
• Take note of the fact that the target status LEDs cannot show MCU status properly after the
emulator is powered on until the emulator debugger gets started.
