Subject: general: Introduce two new headers
X-Git-Tag: v1.0b1~47
X-Git-Url: https://git.htl-mechatronik.at/public/?a=commitdiff_plain;h=0c24f193e260d428283f284672c66be189876727;p=sx%2Fsimavr.git

general: Introduce two new headers

Split the cycle/usec conversion code from the cycle_timer
heacers into it's new sim_time.h

Also removed the simple types out of sim_avr.h to create
new header sim_avr_types.h

Adapted other modules to use avr_time.h
