It looks like a watchdog timer overflow problem. (I had the same problem
with the SAB80535.)
The watchtdog is probably resetting the microcontroller in every xxx ms.

Solution: set up to clear the watchdog before owerflow occurs.

PS: The 80C537 is supported by the header file mcs51reg.h. To obtain 80C537
specific definitions you have to start your program like this:

You have to remove the line #include <sab80515.h> and insert the following
two lines:

#define MICROCONTROLLER_SAB80517
#include <mcs51reg.h>
