This 2-byte register holds the count for the 12-bit reference counter. The
reference counter is shut off and held in reset when the REFON bit is
cleared. For proper operation, this register must not be loaded with a
value less than $000F.
Bit 4 to bit 7 of $000B are not used but they are physically present. The
user may use these four bits for scratch memory.
