FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU18-series device is a 8-tap digitally buffered delay line. The
IN
Signal Input
signal input (IN) is reproduced at the outputs (T1-T8), shifted in time by an
T1-T8 Tap Outputs
amount determined by the device dash number (See Table). For dash

numbers less than 16, the total delay of the line is measured from T1 to
GND Ground
T8. The nominal tap-to-tap delay increment is given by one-seventh of the
total delay, and the inherent delay from IN to T1 is nominally 2.0ns. For dash numbers greater than or
equal to 16, the total delay of the line is measured from IN to T8. The nominal tap-to-tap delay increment is
given by one-eighth of this number.

About the multiplexing of AD channel 0 and UART0
Because all AD channels are used in the design, but AD channel 0 and serial port 0 are multiplexed, I suspect that the code is transferred from UART0 to Flash SPI. In order to avoid conflicts, other U...
