E1/E20 Emulator
Notes on Usage
3.4. MCUs that are used in debugging
MCUs that are connected to the emulator and used in debugging are placed under stress by repeated programming
of flash memory during emulation. Do not use MCUs that were used in debugging in mass-production for end
users.
3.5. FINE communication interface
For the RX63x Group, FINE interface only supports a 2-wire system using FINEC and MD/FINED pins.
The FINEC and MD/FINED pins are exclusively used by the E1 or E20 emulator. Any functions that are
multiplexed on the FINEC pin are not available.
For the RX64x Group, the RX200 Series and RX100 Series, FINE interface supports a 1-wire system using the
MD/FINED pin.
Only the MD/FINED pin is exclusively used by the E1 or E20 emulator. It is not necessary to connect the FINEC
pin since this pin is not used. The FINEC pin can be used as a port.
The external trace-output and real-time RAM monitoring functions via FINE interface are not supported.
Hot plug-ins via FINE interface are not supported.
3.6. High-Speed Clock Oscillator (HOCO)
The emulator uses a device’s internal high-speed clock oscillator (hereafter the HOCO) to achieve communications
with RX200 Series and RX100 Series MCUs. Therefore, the HOCO is always in an oscillating state no matter how
the HOCO-related registers are set.
If there is a contention between switching of the HOCO frequency and memory access, the memory access
operation is not guaranteed.
3.7. Final Evaluation of the User Program
Before entering the mass-production phase, be sure to perform a final evaluation of the program which is written to
a flash ROM using the programming software. Be sure to perform the evaluation singly, without the E1 or E20
emulator connected.
