LCD problem

Started by ramesh babu nalagarla August 12, 2003
Hi Friends!I'am working with MSP430f412 on LCD
interface module.I'am using LCD controller in 4MUX
mode
with following settings.
  LCDCTL = LCDON + LCD4MUX + LCDP1+LCDP0;     
  BTCTL = BTFRFQ1;                      
  P5SEL = 0xFC;    
I'am writing letters 0-9 on LCD infinet loop.But after
some time LCD is not glowing.probably micro may enter
into low power mode.But I'am not calling any low power
calls i.e LPM0....What is the reason.Can any body give
me solution.
My LCD segments pattern is 
               A
             F    B
             
E    C
               D


Thanks & Regards,
Ramesh
