Responding to: ???'s previous message
Save This Code
C:0x0000 850189 MOV TMOD(0x89),0x01
HERE:
C:0x0003 85F28A MOV TL0(0x8A),0xF2
C:0x0006 85FF8C MOV TH0(0x8C),0xFF

You are using direct addressing mode, but you intended to use immediate addressing.
You need to write it as follows:
Save This Code
      MOV  TMOD,#0x01
HERE:
      MOV  TL0,#0xF2

etc.
