Hello! I want to connect my M30853FHFP microcontroller using this scheme in SPI mode (Serial I/O Mode1) can I use this connection scheme from the datasheet? And what pull-up resistors do I need?
The document E8a Emulator Additional Document for User's Manual (Notes on Connecting M32C/84 M32C/85 M32C/86M32C/87 and M32C/88) recommends pull-up /pulld-down resistors of 4.7K or more, see section 5 connection examples using the E8a.
Yes, you are right, I looked at the document, thanks. Can I use this wiring diagram from the MODE1 SPI datasheet?
I assume that you are wanting to connect some type of programmer to this MCU? The datasheet is the generic recommendation, if you are connecting the E8a on-chip debugger or any other Renesas programmer I would recommend following the document's connection example that fits your design.
I would like to know how the M32C differs from the M16C, do they have the same core or not?
I would also like to know what PIN-BUSY is responsible for, and in what documentation I can read about BUSY, in the datasheet I can’t find anything about BUSY, explain to me what it is for.
You should compare the software U/M and hardware U/M between a M16C & M32C to see the obvious differences. Yes they are different cores.

The hardware U/M for M32C/85 documents the BUSY output signal as part of the flash programming signals:
Thank you! tell me what command should I send to the microcontroller to see the bootloader version?
I don't know anything about boot-loader commands, the extent of my experience is connecting the E8a and using FDT to program these devices.
