;   MSP430x42x0 Demo - FLL+, Output MCLK, ACLK Using 32kHz XTAL and DCO
;
;   Description: This program outputs buffered MCLK and ACLK on port pins
;   P1.1 and P1.5.
;   ACLK = LFXT1 = 32768Hz, MCLK = SMCLK = default DCO = 32 x ACLK = 1048576Hz
;   //* An external watch crystal between XIN & XOUT is required for ACLK *//
