5 Notes on Use of EASE1000 V2
5.1 Notes on Debug
(1) About the execution cycle at the wait mode.
On wait mode, STEP execution may differ from the execution cycle of Go- execution.
The final check of an application program should use Go-execution.
(2) About the RAM Match Break
・
The timing of RAM Match Break is after executing a maximum of 3 instruction from the instruction which
read/write access of RAM.
・
The RAM Match Break of DSR (0F000H) cannot choose.
(3) About STOP / HALT mode
The all state such as STOP / STOP-D / HALT / HALT-H (hereinafter called STOP / HALT) will become invalid
the Force break is used in the state of STOP / HALT.
The state of STOP / HALT is canceled by break when Break-point is set up immediately after the instruction
which sets up STOP / HALT.
(4) About Real-Time-Watch
The Real-Time-Watch of DSR (0F000H) cannot choose.
(5) About change of the register value of DTU8 debugger
・
When high-speed clock operation is chosen for target LSI, the FHWUPT register cannot be changed in the SFR
window of DTU8 debugger.
・
When following peripheral is changed by DTU8 debugger, it is set as LSI before an emulation start.
- CPU register: R0, R1, EA, PSW
- SFR: DSR, FCON
(6) About the status window of execution time
The accuracy of Timer displayed in the status window of DTU8 is 100us units. The maximum time which can be
measured is 119 hours. If the maximum time is exceeded, a count will be continued from 0us.
The value of Timer is measured by the timer of EASE1000 V2. Therefore, it differs from the execution time of
LSI. When a measurement period is short, an error of measurement becomes large.
Timer value = Execution time of LSI ± 0.2 % + 300us
5.2 About the 3.3VOUT pin
The specification of the 3.3VOUT pin is 3.3V/100mA.
When using the 3.3VOUT pin with the target system, do not exceed the range of specification.
Using exceeding specification, may damage the target system or EASE1000 V2.
5.3 About Usage Environment
EASE1000 V2 may be affected by the external environment of the host PC, USB cable, EASE1000 V2 interface
cable, and the target system. Please check the operation in the specific customer environment before use.
