 NAME: strata32.c 
 DESC: Strata Flash Programming code through 2443 JTAG  
 HISTORY: 
 JUN.14.2002:LSJ     : ported for 2443 
 Aug.19.2002:purnnamu: ported for 2443 JTAG version. 
 Nov.15.2002:purnnamu: - Fast programming by removing _RESET() in programming loop  
                         and omitting nRCS1 deassertion 
                       - E28F128 ClearLockBit function is added at sector erase step.
