SS_START and SS_STOP must change on the falling edge of
the SYS_CLOCK (Tsetup and Thold > 7.5 ns). Make certain that
the pulse width of both signals is a minimum of 1 SYS_CLOCK
cycle. As long as SS_START or SS_STOP are asserted, the
sequencer stays in a suspended state. (See

Y_START and Y_CLOCK must change on the falling edge of the
SYS_CLOCK (Tsetup and Thold > 7.5 ns). Make certain that the
pulse width is a minimum of one clock cycle for Y_CLOCK and
three clock cycles for Y_START. As long as Y_CLOCK is applied,
the sequencer stays in a suspended state. (See
