Actually, the timer has to be read via ports (to my knowledge). The ports to read are 45h, 46h, 47h, and 48h (I think 48h is one...)
However, this might get tricky since this would have to be done in 32-bits. If you want just a simple timer, you can do something like this:
Asm(EB0E45ED680CED60ED52
The way this will work is that you can run this once with a 0 on the previous line and store the result to a variable. This will be an offset that can be used later. When you run this again, later, make sure the variable with the offset is on the line before. This will then output the number of seconds that have passed since it was used the first time. Um, here is an example:
0
Asm(EB0E45ED680CED60ED52 ;Stores the current timer state to Ans
→T
<<code>>
T ;T will be subtracted from the current timer state
Asm(EB0E45ED680CED60ED52 ;Ans will be the number of seconds (up to 65535) since the timer was initially tested
I don't know if this helps...?
