#82285 - P89C vs P89V Responding to: ???'s previous message |
i am still unable to use the P89V52RD2BN. on P89C51RD2BN i have configured to activate boot loader by RTS and DTR. it is no longer possible now with "V" series.
There is no "funny signals" required for the V series. Start FM and reset the device - thattt's all fffolks. My board has 22.1184 crystal I take you are running in 12 clock mode, the max speed for 6 clock mose is 20MHz. Erik |
