Interface circuit of LPC2200 and PDIUSBD12

Published:2011/7/1 7:19:00 Author:Fiona | Keyword: Interface circuit | From:SeekIC

PDIUSBD12 uses the Bank2 part of LPC2200 external memory control,the data address is 0x82000000, the command address is Ox82000001. RST_USB, SUSP are the LPC2200's output pins, PDIUSBD) 12 interrupt signal is the interrupt input signal and an external interrupt O. C1, C2 and X1 offer PDIUSBD) 12 the clock input for the work.LED GoodLink flickers during normal communication.The AD0 of PDIUSBD12 is connected to the A0 of LPC2200,when the LPC2200 outputs 1 through the A0 pin, it shows that the data which outputs to the PDIUSBD12 data bus DO ~ D7 is command word; When the A0 pin outputs 0,it shows that the data which outputs to the PDIUSBD12 data bus DO ~ D7 is data word.
