National MICROWIRE (COP402)
The COP402 transfers data MSB first and in 4-bit incre-
ments (nibbles). This is easily accommodated by setting
the LTC1290 to MSB-first format and 12-bit word length.
The data output word is then received by the COP402 in
three 4-bit blocks.

Motorola SPI (MC68HC05C4)
The MC68HC05C4 transfers data MSB first and in 8-bit
increments. Programming the LTC1290 for MSB-first
format and 16-bit word length allows the 12-bit data
output to be received by the MPU as two 8-bit bytes with
the final four unused bits filled with zeros by the LTC1290.
