AD7476/AD7477/AD7478 to MC68HC16 Interface
The serial peripheral interface (SPI) on the MC68HC16 is
configured for master mode (MSTR = 1), the clock polarity bit
(CPOL) = 1, and the clock phase bit (CPHA) = 0. The SPI is
configured by writing to the SPI Control Register (SPCR). For
more information on the MC68HC16, check with Motorola for
the related documentation.

The serial transfer takes place as a 16-bit operation when the
SIZE bit in the SPCR register is set to SIZE = 1. To implement
the power-down mode with an 8-bit transfer, set SIZE = 0.
A connection diagram is shown in Figure 21.
