+; blink.asm - simple ASM example to toggle a port pin
+;   (LED on TINI board).
+;
+;   On a TINI board this toggles really fast, so
+;   it appears that the LED just dims slightly.
+;   You may need a scope to detect it.
+;
+;  You can use s51(ucsim simulator) to look at the
+;  blink.ihx(hex-file).  Run like this:
+;  >S51 blink.ihx
+;  Then dump code like this:
+;  s51>dc
