Page 8 Changed to generic pin naming since many different
LPCXpresso target boards exist.
I2C peripherals
Rev B
Added J60/J61/R216/R217 (page 5) for USB Host i/f.
Page 9 Added J62 (page 6) to support LPC17xx bootload.
Added J58 (page 10) to support spi i/f to OLED or mbed.

However, always check jumper positions on actual boards
since there is no guarantee that all jumpers are in default place.
