 +==== Program ​ Code  Memory ​ Write  Enable ​ Bit ====
 +<​nowiki>​
 +Inside ​ the  PCON  register, ​ the  Program ​ Write  Enable ​ (PWE)  bit  is  used  to  enable/​disable ​
 +Program Write signal activity during MOVX instructions. ​  
 +When the PWE bit is set to logic ‗1', the ―MOVX @DPTR, A‖ instruction writes the data from 
 +the accumulator register into the code memory addressed by using the DPTR register (active ​
 +DPH:​DPL) ​
 +  The ―MOVX ​ @Rx,  A‖ instruction writes ​ the data from the accumulator register into code 
 +memory addressed by using the P2 register (bits 15:8) and Rx register (bits 7:0).
