       Use the following formula to calculate the 10-bit value for a particular frequency:
 
-      $$ n = clock_{frequency} / (32 * note_{frequency}) $$
+      $$ tone period_{cycles} = clock_{frequency} / (32_{cycles} * note_{frequency}) $$
 
       For example 10-bit value that plays 440 Hz note on a chip clocked at 4 MHz would be:
 
-      $$ n = 4000000 Hz / (32 * 400 Hz) = 284 $$ 
+      $$ tone period_{cycles} = 4000000 Hz / (32_{cycles} * 400 Hz) = 284 = 11C_{hex} $$
