Access to CNT register

tomcrawford

I apparently have suffered drain bamage. I cannot find how to read the cnt register. If I say

mov  stime, cnt      'get pulse start time

it says "error symbol cnt is not constant".

Please help.

For prop2, use GETCT instruction. WAITCNT is replaced by WAITCTx and ADDCTx for x=1,2,3

        getct   stime

Hmm... I wonder how the new 64-bit CT register will handle rollover for wait and add...

Guess it works out to be the same as with 32 bit CT register...

Same as it does now. The only change is the cnt is extended to 64 bits and you can read the high 32bits. Otherwise those top 32 bits are hidden/unused.
