Renesas CE2000-H8S Series, User Manual

Page: 44 / 96

3.2 Programmable Function Generator (PFG)
This allows user to download the desired emulation function during debugging (in Options->Emulator-
>System…) . At the power-up state, there is no function in the PFG and user has to download the
preferred function before emulation. User can only change the function when the emulator is in break
mode. To access the function after downloading, user has to open up the break or trace window. The
programmed function will remain in the emulator as long as it is not powered down.
As at the current date, the available function is the “Integrated 256 Cycles of Bus Trace and Two Event
Breaks”. More functions will be generated later. Please approach the relevant Renesas Sales Office for
further information.
3.3 Pin View
Pin View module shows the pin-state of device in graphical and text forms.
3.4 Go (Reset Go, Go at PC, Goto Cursor)
Real-time execution (in Debug/Go) by the H8S chip based on the user setting. There is no “cycle steal“
during the execution mode.
3.5 Reset CPU
When ”RESET CPU” command is activated, the following actions will take place,
PC = Power on Reset vector value
ER7 = H’FFEFBC
ER0-6 = H’0
CCR = H’80
EXR = H’07
The microcomputer is reset.
3.6 Single-Step
There are four types of Single Step:
•
Step-In,
•
Step-Over, Step-out,
•
Step…
Single Step executes the instruction at the current program counter. If an interrupt is asserted, the
interrupt service routine will not be serviced unless a “Go” commands is issued.
Step-In will execute a single instruction only. For C source file, a single step will execute a “single C
source code”. Whereas for an assembly file, a single step will execute a single assembly instruction code.
Step-Over executes multiple Step-In to complete a function execution until it has reached the next
instruction.
