Hi All, I am facing a reset problem in LPC2214. The problem is limited to improper operation of SPI peripheral, when using a RC reset or a supervisory IC TPS3125J18. But, if i use a simple reset switch arrangement, which shorts the Reset pin to ground momentarily and then pulling the Reset pin high through a resistor of 10k then, the SPI operation seems to work properly. As we are developing a commercial application, this type of reset switch operation would not be desirable. I am unable to understand, why only the SPI should malfunction. If at all there is a reset problem, then why should there be no problem in the functioning of the other peripherals. And also, why should the problem be resolved by the provision of a reset s/w. I hope some one can guide me in this respect. Regards, Jerome --------------------------------- Jiyo cricket on Yahoo! India cricket [Non-text portions of this message have been removed]
