IMPORTANT

Note on NMI* Input:

 L" input from the user system to pin NMI* is accepted only while a user program is being executed

(only while the RUN status LED on the PC4701's front panel is lit).

Note on RDY* Input:

 Be sure to input "L" to pin RDY* of the user system during the user program executing (only while the

RUN status LED on the PC4701's front panel is lit). Inputting "L" to pin RDY* during the user

program stopping may cause a malfunction of the emulator.

Note on HOLD* Input:

 You cannot use the hold function with this product. Be sure to input "H" to pin HOLD* of the user

system when you use a processor mode other than single-chip mode. If "L" is input to pin HOLD*, this

product will not work normally.

Notes on Maskable Interrupts:

 Even if a user program is not being executed (including when run-time debugging is being performed),

the evaluation MCU keeps running so as to control the emulation pod. If a maskable interrupt is

requested when the user program is not being executed (including when run-time debugging is being

performed), the maskable interrupt request cannot be accepted, because the emulator disables

interrupts. The interrupt request is accepted immediately after the user program execution is started.

 Take note that when the user program is not being executed (including when run-time debugging is

being performed), a peripheral I/O interruption is not accepted.

Note on DMA Transfer:

 With this product, the program is stopped with a loop program to a specific address. Therefore, if a

DMA request is generated while the program is stopped, a DMA transfer is executed, but it may not be

performed correctly. Also note that the below registers have been changed to generate a DMA transfer

as explained here even when the program is stopped.

DMA0 and DMA1 transfer counter registers : TCR0 and TCR1

Note on Pullup Control:

 With this product, ports P0 to P5 are not pulled up by the pullup control register. To pull up the ports

P0 to P5, mount the included network resistor (51 kΩ) to the inside of the emulator as occasion

demands. How to mount it, refer to "2.5 Installing and Removing Network Resistors for Pullup" (page

30).

*Note: Ports P6 to P10 are pulled up by the pullup control registers.

*Note: Pullup control registers themselves can be read and written into properly.

Note on Final Evaluation:

 Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate

your system and make final confirmation with a CS (Commercial Sample) version MCU.
