Andreas,
According to page 43 of the 1893 spec, bits[6:0] are the block count
and read-only. They are reset by either a master reset (hardware or
software) or toggling bit[7] from its default of 1->0->1. As the counter
is only 7 bits, it seemed reasonable to automatically reset it when read.
The code snippets would seem to perform identically.
Hope this helps,
Steve
