Serial Console
==============
The LPC4330 Xplorer does not have RS-232 drivers or serial connectors on board.
USART0 and UART1 are available on J8 as follows:
------ ------ -----------------------
SIGNAL J8 PIN LPC4330FET100 PIN
(TFBGA100 package)
------ ------ -----------------------
U0_TXD pin 9 F6 P6_4 U0_TXD=Alt 2
U0_RXD pin 10 F9 P6_5 U0_RXD=Alt 2
U1_TXD pin 13 H8 P1_13 U1_TXD=Alt 1
U1_RXD pin 14 J8 P1_14 U1_RXD=Alt 1
------ ------ -----------------------
FPU
