{PERAMCNT [1:0], PERAML [7:0]}: Define the starting RAM address [9:0], which stores the data wanted to be  
programmed. The valid RAM addresses are 00H ~ 07FH and 0100H ~ 01FFH.  
PERAMCNT [7:3]: Defines the number of words wanted to be programmed. The maximum PERAMCNT [7:3] is 01FH,  
which program 32 words (64 bytes RAM) to the Flash. The minimum PERAMCNT [7:3] is 00H, which program only 1  
word to the Flash.
