AD7898 to MC68HC16 Interface
The Serial Peripheral Interface (SPI) on the MC68HC16 is
configured for Master Mode (MSTR = 1), Clock Polarity Bit
(CPOL) = 1 and the Clock Phase Bit (CPHA) = 0. The SPI is
configured by writing to the SPI Control Register (SPCR) (see
68HC16 user manual). The serial transfer will take place as a
16-bit operation when the SIZE bit in the SPCR register is set
to SIZE = 1. To implement the power-down modes with an
8-bit transfer set SIZE = 0. A connection diagram is shown in
Figure 20. The V
DRIVE
pin of the AD7898 takes the same sup-
ply voltage as that of the MC68HC16. This allows the ADC
to operate at a higher voltage than the serial interface, i.e.,
MC68HC16, if necessary.
