nuc710使用注意点

#LCD MAC SD不冲突
LCD VD[0]-VD[7] -- P.34 - P.41
VD[8]-VD[15] -- P.52 - P59 (P.42-P.49与MAC,SD,SC,KPI冲突)
MAC和KPI冲突
SD和SC冲突
I2C和SPI冲突
Audio和UART3冲突,PWM
PS2和UART2，UART1 CTS/RTS冲突

===========================================================
710 NAND
因为W90P710本身不支持NAND flash设备,所以通过采用总线信号硬件译码产生NAND flash
的控制信号.如下:
引脚名称 引脚号 功能名称 说明
A[0] 89 CLE NAND flash命令锁存
A[1] 90 ALE NAND flash地址锁存
nECS[0] 130 nFCE NAND flash片选(系统自动产生)
nOE 131 nOE NAND flash输出使能(系统自动产生)
D[0]-D[7] 176-168 D[0]-D[7] NAND flash 数据(8bit)

两个USB Host
==============================================================
Software 找地方加一行 code : *(unsigned int volatile *)(0xfff00030) = 0x1;

才能用两个usb host

USBTXRCON
USBHnD[0]: USB transceiver control
There are two USB1.1 built-in transceivers. One is a dedicated USB
host, and the other is shared with USB device. This bit can be set in
software to toggle the transceiver path.
1 = HOST
0 = Device
