+In order to qualify for fast bitmap processing, the array must meet the
 following requirements:
-- it must belong to the same chip as other 'fast' pins of the function,
-- its index within the function must match its hardware number within the chip.
+- pin hardware number of array member 0 must also be 0,
+- pin hardware numbers of consecutive array members which belong to the same
+  chip as member 0 does must also match their array indexes.
 
-Open drain and open source pins are excluded from fast bitmap output processing.
+Otherwise fast bitmap processing path is not used in order to avoid consecutive
+pins which belong to the same chip but are not in hardware order being processed
+separately.
+
+If the array applies for fast bitmap processing path, pins which belong to
+different chips than member 0 does, as well as those with indexes different from
+their hardware pin numbers, are excluded from the fast path, both input and
+output.  Moreover, open drain and open source pins are excluded from fast bitmap
+output processing.
