Reading of register value is not supported.
For Analog Audio Processors, How should unused output pins be handled?
Unused output pins can be left OPEN.
For Analog Audio Processors, Why is the noise level higher when EQ is on than when EQ is off?
When the EQ is off, the signal does not pass through the equalizer circuit.

Does the A/D converter include a sample/hold circuit? Or, does a hold occur for the number of input ports?
The ADC of our microcontroller includes a sample/hold circuit. Note that the sample/hold circuits for the number of input ports are not provided.
The following error occurred after a build attempt using the standard library. Error E010: Unresolved external symbol '__***'
This error is output because the standard library is not specified by IDEU8. Specify one of the following four libraries for the IDEU8 target option [Add to Library Field] according to the use condition. lu8100sw.lib Small model, pack function unsupported lu8100lw.lib Large model, pack function unsupported lu8100swpk.lib Small model, pack function supported lu8100lwpk.lib Large model, pack function supported See “RTLU8 Runtime Library Reference Manual” for details of libraries.

I created a library file using LIBU8, but some of them were not imported. For example, it is a source code (file) in which an interrupt function is defined. All the interrupt functions are static functions. Is it possible to create it as a library in such a case?
Files containing statically declared functions can be registered in library files. However, since it cannot be referenced from the outside, the module in the library cannot be found, and an error occurs when linking and it cannot be used. Create the function to be registered in the library as a global function.
Is there any way to avoid receiving data during CCA?
To prevent data reception during CCA, follow the steps shown below. To restore data reception after CCA, be sure to return to the original setting before reception. [Procedure] (1) Setting to prevent bit synchronization from being established BANK1: 0x5C = 0x00 BANK3: 0x03 = 0x00 (2) CCA started (3) Waiting for CCA completion (4) After completion of CCA, TRX_OFF (1) Setting to establish bit synchronization BANK1: 0x5C = original value BANK3: 0x03 = original value Related Products: ML7345 family
When creating a Hex file using HTU8, are two ROM code data files, "RA" and "RB", generated without /F option?
Yes. Regardless of /F option specified/not specified, two ROM code data files, "RA" and "RB", are generated. /F option is an option to specify a ROM code data filename output by HTU8. When /F is removed, a filename is automatically determined using the input file specified on the head by HTU8 as the base name of output file. /F option specified: HTU8 test01.hex /TM610439 /FML610Q439_000 /OH *When above is executed in a command prompt for U8, the following three output files of HTU8 are output. ML610Q439_000RA.HEX ML610Q439_000RB.HEX ML610Q439_000RA.log /F option not specified: HTU8 test01.hex /TM610439 /OH *When above is executed in a command prompt for U8, the following three output files of HTU8 are output. TEST01RA.HEX TEST01RB.HEX TEST01RA.log *The four ROM code data contents of ML610Q439_000RA.HEX, ML610Q439_000RB.HEX, TEST01RA.HEX, and TEST01RB.HEX are identical. Related Products: ML610Q43x
Is there any way to avoid receiving data during CCA?
To prevent data reception during CCA, follow the steps shown below. To restore data reception after CCA, be sure to return to the original setting before reception.

The following error occurred after an attempt to connect a debugger using on-chip emulator: “ICE error: 6307H Failed to start on-chip ICE block.” What should I do?
The ICE error: 6307H is caused by the following situations. (1) Poor connection between the on-chip emulator and microcontroller. (2) Microcontroller failure. (3) For the microcontroller on which the test pin and general-purpose port are shared, output port is set by a program. An error caused by (1) can be avoided by connecting the on-chip emulator and microcontroller properly. For a reference board, check that jumpers are set on the on-chip emulator side. When there is no problem with connection, (2) or (3) may be the case. Replace the target LSI.
What happens when the compiler option [Delete padding of structure/shared member] is checked with IDEU8?
When [Delete padding of structure/shared member] is checked with IDEU8, /Zp option is specified for CCU8 compiler to execute. In this case, padding is not inserted between members for the case where all structure/shared members are char type. See “11.3 Structure/Shared Member Arrangement” in “CCU8 User's Manual” for member arrangement.
