+ * Program RAM (pram), which has a size of 16K, but
+ * also has to accomodate the stack the device uses,
+ * which starts at the top of the 16k, so we pretend
+ * that we just have 16256 (16k - 128) of pram.
+ *
+ * This section documents some of the other areas
+ * mapped into the firmware processor's address space
+ * as well.
