The pin n°17 of the LPC2148 connects or disconnects the USB, tying up the 1,5Kohm resistor to the USB D+ signal. The Set Device Status Register, bit 0 "CON", defines the SoftConnect function but does not define the polarity (one or zero) of the output pin, when the "CON" is programmed in "1". Could anyone send me the information about the output signal level when connect is activated? Regards, Jan [Non-text portions of this message have been removed]
