AD7887 to MC68HC11
The serial peripheral interface (SPI) on the MC68HC11 is
configured for master mode (MSTR = 1) when the clock
polarity bit (CPOL) = 1 and the clock phase bit (CPHA) = 1.
The SPI is configured by writing to the SPI Control Register
(SPCR)—see the M68HC11 reference manual from Freescale
Semiconductor, Inc., for more information. The serial transfer
takes place as two 8-bit operations. A connection diagram is
shown in Figure 25.

The PIC16C6x synchronous serial port (SSP) is configured as an
SPI master with the clock polarity bit = 1. This is done by writing to
the synchronous serial port control register (SSPCON). See the
PIC16/PIC17 Microcontroller User Manual. Figure 27 shows the
hardware connections needed to interface to the PIC16C6x/
PIC16C7x. In this example, input/output port RA1 is being used to
pulse CS. This microcontroller only transfers eight bits of data
during each serial transfer operation. Therefore, two consecutive
read/write operations are needed.

It is possible to implement a serial interface using the data ports
on the 8051. This allows a full duplex serial transfer to be imple-
mented. The technique involves bit-banging an input/output
port (for example, P1.0) to generate a serial clock and using two
other input/output ports (for example, P1.1 and P1.2) to shift
data in and out—see Figure 26.
