AD7466/67/68 to MC68HC16
The Serial Peripheral Interface (SPI) on the MC68HC16
is configured for Master Mode (MSTR = 1), Clock Po-
larity 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. A con-
nection diagram is shown in figure 21.
