LCD1602+908JL16

Hi,all
 
I need to port LCD1602 to 908JL16CPE.
For we don't have many pins on JL16CPE, I need to configure LCD1602 as 4bit dataline,2 lines display,5*7 dot character.
I followed AN2940 "LCD Driver for the HC08/HCS08 Family" but it didn't work.
It appears not well initialized or I don't know any other possibilities.
Afer power on, the first line of LCD1602 displays all black blocks. and no chars displayed.
 
I assume this is the result of insufficient initialization,is it right? or what?
 
If anyone would provide me a tested LCD1602 subroutine example for HC908mcu, that will be great thanks.
 
Regard,
