Comments
The nibbles are
mirrored so that LSB
or MSB first mode
registers correctly,
regardless of shift
mode
Unique chip ID used
to differentiate
devices; read only
Unique speed grade
ID used to
differentiate devices;
Read only
Synchronously
transfers data from
the master shift
register to the slave
Determines various
generic modes of
chip operation
The divide ratio is
the value plus 1
When set, the test
data is placed on the
output pins in place
of normal data
When Bit 0 is set, the
built-in self-test
function is initiated
