FAQ NO : 1010341 Issue Date : Mar.18.13 Functions : Reset When bits HWR, SWR, and WDR in the reset source determination register (RSTFR) are set to 0? Bits HWR, SWR, and WDR are exclusive. When a flag (e.g. HWR bit) is set to 1, other flags (bits SWR and WDR) are set to 0. Relevant Products R8C/3x R8C/5x R8C/Lx R8C/Mx
FAQ NO : 1010110 Issue Date : Aug.09.12 Functions : A/D Converter What is the definition of the A/D converter absolute accuracy described in the Electrical Characteristics? The accuracy of the A/D Converter is indicated by an absolute accuracy. The absolute accuracy refers to a difference expressed by LSB between the output code obtained by A/D converting the analog input voltages and the output code expected for an A/D ...

FAQ NO : 1010108 Issue Date : Aug.09.12 Functions : Two-Phase Encoder Input I am trying to generate an interrupt at the compare match timing in phase counting mode of timer RG, but the interrupt is not generating even though registers TRG and TRGGRA match. A compare match signal is generated at the last state when the TRG register and the TRGGRA register match (at the timing for updating the count value that the TRG register matches). After registers TRG and TRGGRA match, a compare match signal is gener...

FAQ NO : 1010107 Issue Date : Aug.09.12 Functions : I2C-bus What is the procedure for regenerating the start condition for the I2C bus interface? Regenerate the start condition while bus is busy (BBSY bit is 1) and set the associated registers in the same way the start condition is generated. You do not need to generate a stop condition.

FAQ NO : 102411 Issue Date : Jun.28.12 Functions : CPU I inserted multiple NOP instructions to set an accurate time interval. Butthis does not provide an accurate time interval (NOP instruction executioncycles X number of instructions). Why is that? M16C Family has a queue buffer which pre-fetches instruction codes while the bus is not busy. Each instruction execution cycle listed in the software manual is a value based on this condition (the instruction is already in the queue buffer). If ...

FAQ NO : 1009991 Issue Date : Apr.02.12 Functions : DTC/DMACII When a DTC activation source is generated while the CPU executes interrupt handling, is the DTC activated immediately, after interrupt handling is completed, or depending on the priority order of interrupt sources? The DTC is activated immediately. The DTC and CPU use the same bus, and the DTC takes priority over the CPU in using the bus. The DTC takes priority regardless of the priority of interrupt sources.

FAQ NO : 106416 Issue Date : Mar.15.12 Functions : I/O Register/SFR The manual describes some bits as follows: "Nothing is assigned. In anattempt to write to these bits, write "0". The value, if read, turnsout to be indeterminate." For other bits that are assigned to the same address with the above bits, canwe use read-mod...
