1 Channel enable bits do not require an I/O update to be activated. These bits are active immediately after the byte containing the bits is written. All other bits need an
I/O update to become active. The four channel enable bits shown in Table 28 are used to enable/disable any combination of the four channels. The default for all four
channels is enabled.
In the channel select register, if the user wants four different
frequencies for all four DDS channels, use the following
protocol:
1.
Enable (Logic 1) the Channel 0 enable bit, which is located
in the channel select register, and disable the other three
channels (Logic 0).
2.
Write the desired frequency tuning word for Channel 0, as
described in Step 1, and then disable the Channel 0 enable
bit (Logic 0).
3.
Enable the Channel 1 enable bit only, located in the
channel select register, and disable the other three
channels.
4.
Write the desired frequency tuning word for Channel 1 in
Step 3, then disable the Channel 1 enable bit.
