FAQ NO : 1000375 Issue Date : Apr.07.11 Functions : A/D Converter , I/O Port Regarding AD input ports, can half be set to AD input ports and the other half to general input ports? No, AD input ports and general input ports cannot be used together.The PORT register reads the pin status in 8-bit units.Therefore, if the PORT register is read while analog voltage is being applied to an AD input port, the pin being used an AD input ...

FAQ NO : 1000374 Issue Date : Apr.07.11 Functions : PWM Output In the timer pulse unit (TPU), can two different PWM outputs be enabled for a channel that has four TGR registers using PWM mode 1? Two different pins, TIOCA and TIOCC, are capable of PWM output. However, the output cycle will be the same because they share a counter.To output PWM with a different cycle, please use a separate channel. Relevant Products H8S Family H8SX Family
FAQ NO : 1000373 Issue Date : Apr.07.11 Functions : Serial Interface What is the right timing for parity error (PER) detection, at parity bit reception or at stop bit reception? The parity error bit (PER) will be set at reception of the stop bit.This is the same timing as that of flaming error shown in Figure "Example of Operation for Reception in Clock Synchronous Mode" (8-bit data/parity/1 stop bit example) in the hardware ...

FAQ NO : 1000372 Issue Date : Apr.07.11 Functions : Electrical Characteristics Is there any acceptable level of overshoot/undershoot (for pulse width and power voltage)? No. There is no acceptable level over or below the specified value. Please use within the range written in the hardware manual (within VIH max and min values).

FAQ NO : 1000371 Issue Date : Apr.07.11 Functions : Oscillation Circuit , General (Clock) In the Clock Pulse Generator section of the manual, the table Crystal Oscillator Characteristics shows max Rs resistance. Can I use a higher resistance Crystal Oscillator? The resistance value and capacitance value described in the table Characteristics of Crystal Oscillator are only for reference. Please ask your oscillator's manufacturer for matching characteristics measurements and determine resistance and capacitanc... Relevant Products H8S Family H8SX Family
FAQ NO : 1000370 Issue Date : Apr.07.11 Functions : Bus State Controller/External Bus Interface In Section 9 (BSC)/Features, it says "8-bit access or 16-bit access can be selected for each area" but for the bus width controller register (ABWCR), it says "If any area is designed as 16-bit access space, 16-bit bus mode is set". If 16-bit bus width is s... Yes. You can select 8-bit access area/16-bit access area by area, for example selecting 8-bit bus width for one area and 16-bit bus width for another area. However, if there is a 16-bit bus width in any external bus area, the data bus will require 16 ... Relevant Products H8S Family H8SX Family
FAQ NO : 1000368 Issue Date : Apr.07.11 Functions : Flash Memory Does the NWEC min value of internal flash memory rewrite number mean one cannot program after programming over the minimum value? No. You can program the internal flash memory over the NWEC minimum value (100 times), but the programming time (tP), erasing time (eE), total programming time (ΣtP), total erasing time (ΣtE), total programming/erasing time (ΣtPE) and data retain time...

FAQ NO : 1000369 Issue Date : Mar.31.11 Functions : Serial Interface When the SCI is used in for external clock input in clock synchronous mode, how should I set the values of bits CKS 1 to 0 and the bitrate register (BRR) in the serial mode register (SMR)? Bits CKS 1to 0 and BRR in SMR are not used for external clock input. Therefore, there is no need to set bits CKS 1to 0 and BRR in SMR. Relevant Products H8S Family H8SX Family
FAQ NO : 105720 Issue Date : Mar.18.09 Functions : A/D Converter I do not understand the linkage between the setup of the conversion time of the A/D converter, and minimum conversion time, which is on the A/D conversion characteristics section of electrical characteristics of the hardware manual. Depending on the operating frequency and the setting value that you are using, it can be possible to setup the conversion time, which is lower than the minimum conversion time of electrical characteristics, but in that case, accurate conversion r...

FAQ NO : 105572 Issue Date : Mar.18.09 Functions : Serial Interface 1 bit misalignment occurs with received data when using synchronous mode. There is no problem found in the waveform. What caused this problem? How do I fix it? The serial interface of the H8 family and the H8S family is divided into a transmit part and a receive part structurally to be used for both asynchronous and functions.
