This is the timer program for the 12c5a chip.

I copied him directly to the 89c52.
It is reasonable to change to the 89c52 chip when it is universal
But it is stuck in this timer program.

I tested this way.
The serial port can only receive 0x11
Then the following program did not respond.
Please answer your questions. Thank you.
