Default Notes/
Comments
The nibbles
should be
mirrored so that
LSB- or MSB-first
mode is set cor-
rectly regardless
of shift mode.
Default is unique
chip ID, different
for each device.
This is a read-
only register.
Child ID used to
differentiate
graded devices.
Bits are set to
determine which
on-chip device
receives the next
write command.
Bits are set to
determine which
on-chip device
receives the next
write command.
Synchronously
transfers data
from the master
shift register to
the slave.
Determines
various generic
modes of chip
operation.
Turns the
internal duty
cycle stabilizer
on and off.
When this reg-
ister is set, the
test data is placed
on the output
pins in place of
normal data.
