The software provided with the CDB61880 evalu-
ation board is used to control and monitor the

matically read back each bit after each write. If the
bit is read back incorrectly an error will occur. The
following registers do not have the automatic read
back function:
- AWG Phase Address
- AWG Phase Data,
- Software Reset registers.
