;   MSP-FET430P140 Demo - Basic Clock, Output Buffered SMCLK, ACLK and MCLK
;
;   Description: Output buffered MCLK, SMCLK and ACLK.
;   ACLK = LFXT1 = 32768Hz, MCLK = DCO Max, SMCLK = XT2
;   //* XTAL's REQUIRED - NOT INSTALLED ON FET *//
;   //* Min Vcc required varies with MCLK frequency - refer to datasheet *//
