LPC812 NXP Xpresso board System Init code

Detailed Description

The System initialization code is called prior to the application and initializes the board for run-time operation. Board initialization for the NXP LPC812 board includes default pin muxing and clock setup configuration.

With the exception of stack space, no RW memory is used for this call.
