- Note on changing the count source protection mode after reset select bit (CSPROINI)
- Note on changing the count source protection mode after reset select bit (CSPROINI)
- Note on the port XIN-XOUT switch bit (CM13)

- Note on holding the error flags in serial interfaces
When you change the bit 7 (CSPROINI) of the Option Function Select Register (OFS at
address 0FFFFh), by rewriting directly or downloading, the reset operation from the
emulator should be done twice or more. Otherwise, the alteration may not be reflected.
After changing the bit 3 (CM13) of the System Clock Control Register 1 (CM1 at address
00007h) to “1”, do not set it to “0”. Otherwise, the emulator cannot be operated normally.
When you change the bit 7 (CSPROINI) of the Option Function Select Register (OFS at
address 0FFFFh), by rewriting directly or downloading, the reset operation from the
emulator should be done twice or more. Otherwise, the alteration may not be reflected.
Debugging in CPU rewrite mode where the Erase Suspend function is enabled (FMR40
= “1”) cannot be executed. Furthermore, the Block Erase and Byte Program times during
CPU rewrite differ with those of the actual MCU.
When bit 3 (STOP) of the IIC Bus Status Register (ICSR at address 000BCh) is read out,
its value is indeterminate.
When you change the bit 7 (CSPROINI) of the Option Function Select Register (OFS at
address 0FFFFh), by rewriting directly or downloading, the reset operation from the
emulator should be done twice or more. Otherwise, the alteration may not be reflected.
In the memory window, ASM watch window and script window of the emulator debugger,
if you reference or modify the SFR area in word, all the areas will be accessed by byte
except for some areas of the timer RD related register (00146h--0014Fh,
00156h--0015Fh).
Note that the SFR area can be accessed from the user program, as specified in the
program.
The clear conditions of the overrun error flag (OER) when using the clock synchronous
serial I/O mode and the clock asynchronous serial I/O (UART) mode, and the framing
error flag (FER) and the parity error flag (PER) when using the clock asynchronous serial
I/O (UART) mode are different form the actual MCU.

The maximum ROM capacity supported by this product is 112 Kbytes. Therefore, you
cannot debug a program larger than 112 Kbytes. The following shows the Flash Memory
Block Diagram for when using with this product, taking the R8C/22 and /23 groups as an
example.
