 		 #86048 - Thus I use assembler !
Responding to: ???'s previous message
Erik Malund said:

Oh, what if you, without stopping the timer, read ff from the low byte and then read the high byte, you will read 100h too much.


Again:

Reading FF by replacing with 00 can never cause an overflow !!!

This is the meaning of the XCH instruction.

And thus assembler was needed to do so.
