12-Bit End of Packet 0111 1111 1110
A 38-bit serial word is used, divided into 6 fields. Assuming
each bit can be loaded in 60 μs, the 38-bit serial word transfers
in 2.3 ms. Table 10 summarizes the word format.
Field 0 and Field 5 are the start-of-packet field and end-of-
packet field, respectively. Matching the start-of-packet field with
1000 0000 0001 and the end-of-packet field with 0111 1111
1110 ensures that the serial word is valid and enables decoding
of the other fields.
Field 3 breaks up the data and ensures that no data combination
can inadvertently trigger the start-of-packet and end-of-packet
fields. Field 0 should be written first and Field 5 written last.
Within each field, the MSB must be written first and the LSB
written last. The shift register features power-on reset to minimize
the risk of inadvertent programming; power-on reset occurs
when VDD is between 0.7 V and 2.2 V.
