i'm using winstar 16*2 char lcd for displaying volume byte on screen.this lcd is interfaced with MC9S08SE8 MCU.i'm controlling the volume by pt2258 .after running the asm program and increasing the volume by remote .it is displaying the correct sequence of volume bytes but when i continue to press the volume button it abruptly stops displaying the correct sequence and displays garbage characters and then the lcd display is turned off.
