68300

Hello List,

I am trying to write a 32 bit timer routine in TPU microcode for the TPU 
in a 68376.

I seem to be having a timing problem when a match = $0000 (MRL = 1) and the micro instruction 

p:= ert;
ram p -> @LYD_TIMER_B.

For my application I need a high resolution (200nS) and measurements down to .1Hz.

Has anybody been able to implement a 32 bit timer on the TPU to measure frequency.

I would like to hear from somebody who any knowledge on the subject.
