8MHZ crystal oscillator checking??

Other Parts Discussed in Thread: MSP430F149, MSP430F155

hi all.

  i got this code from ti example to add a external oscillator 8 mhz and its working properly  i got the 8 mhz frequency output  by means of reading the p5.4 pin.. and i did the slight modification i just included  the for loop to set and reset the port pin  p1.0 here the problem is if am checking the frequency at p1.0 means instead 8mhz  am getting only 0.8mhz .. what s the problem?? in the below code?

//  MSP-FET430P140 Demo - Basic Clock, MCLK Sourced from HF XTAL
//
//  Description: Proper selection of an external HF XTAL for MCLK is shown by
//  first polling the OSC fault until XTAL is stable - only then is MCLK
//  sourced by LFXT1.  MCLK is on P5.4
//  ACLK= MCLK= LFXT1= HF XTAL
//  //* HF XTAL NOT INSTALLED ON FET *//
//  //* Min Vcc required varies with MCLK frequency - refer to datasheet *//
