System Clock. The TMC2249A operates from a single master
clock input. The rising edge of clock strobes all enabled registers.
All timing specifications are referenced to the rising edge of CLK.

A-D Input. A through D are the four 12-bit registered data input
ports. A0-D0 are the LSBs (see Table 1). Data presented to the input
ports is clocked in to the top of the 16-stage delay pipeline on the
next clock when enabled, "pushing" data down the register stack.

A-D Delay. ADEL through DDEL are the four-bit registered input
data pipe delay select word inputs. Data to be presented to the
multipliers is selected from one of sixteen stages in the input data
delay pipe registers, as indicated by the delay select word
presented to the respective input port during that clock. The
minimum delay is one clock (select word=0000), and the maximum
delay is 16 clocks (select word=1111). Following powerup these
values are indeterminate and must be initialized by the user.

the LSB. See Table 1.

Sum Output. The current 16-bit result is available at the Sum
output. The output may be the most or least significant 16 bits of the
current accumulator output, as determined by SWAP. S0 is the LSB.
See Table 1.
