FAQ NO : 105328 Issue Date : Sep.09.11 Functions : Pin Can several unused pins be collectively pulled-up or pulled-down with one resistor? It is NOT recommended that several unused pins collectively pull-up or pull-down with one resistor. The reason is that excessive current flows to the pins and output element may be destroyed when CPU can be runaway from some causes and the setting o...

FAQ NO : 1000594 Issue Date : Sep.09.11 Functions : Flash Memory Is there anything I should consider when I transit the mode of FCU as the sequencer for the internal ROM and data flash? For FCU mode transition, you should set the flash P/E mode entry register (FENTRYR). When you would lie to set the EFNTRYR, be sure to dummy read it right after writing the FENTRYR setting value. Then, write ROM/FLD, delete and read. ... Relevant Products SH7214, SH7216 SH7239, SH7237
FAQ NO : 1000593 Issue Date : Sep.09.11 Functions : Flash Memory I cannot write to the internal flash memory with the MCU in boot mode. Please indicate the points to check to solve this problem. Please check the following points. ・Power-on reset is correct.‐Reset signal is cleared after the oscillation is stabilized at the time of power-on.‐The hardware stand-by pin (HSTBY) is not switched to Low at power-on if your MCU has a stand-by fu...

FAQ NO : 1000590 Issue Date : Sep.09.11 Functions : Serial Interface hen I transmit the RSPI using DTC, the transmitted data are reduced from the set value by one piece. Is there any specific point that I need to pay attention for using DTC? DTC final transfer doesn't clear the RSPI transmit buffer empty flag (SPTEF flag). It is necessary to clear SPTEF flag by the RSPI transmit buffer empty interrupt.Without that process, the final transmit data is not transferred from the buffer to t...
