I am trying to use PK51 to program/flash P89LV51RC2 using ISP (In-System Programming). However, PK51 sends character 0xA5 instead of 0x55 ("U") during autobaud phase, which causes P89LV51RC2 to not enter into ISP.
Flash Magic works correctly and I can use it to flash P89LV51RC2 without problem.
Help is greatly appreciated.
