2.4
The programming module operates
command sequences entered in serial fashion with the
data being latched on the falling edge of the clock
pulse. The sequences are entered serially, via the clock
and data lines, which are Schmitt Trigger inputs in this
mode. The general form for all command sequences
consists of a 6-bit command and conditionally a 16-bit
data word. Both command and data word are clocked
LSb first.
The signal on pin DATA is required to have a minimum
setup and hold time (see AC/DC specifications), with
respect to the falling edge of the clock. Commands that
have data associated with them (Read and Load),
require a minimum delay of T
command and the data.
The 6-bit command sequences are shown in Table 2-3.
