TECHNICAL DATA

Figure 6-3
illustrates the MOSI, MISO, SCK, and SS master-slave interconnections.
Due to data direction register control of SPI outputs and the port D wire-OR mode
(DWOM) option, the SPI system can be configured in a variety of ways. Systems with
a single bidirectional data path rather than separate MISO and MOSI paths can be ac-
commodated. Since MC68HC11A8 SPI slaves can selectively disable their MISO out-
put, a broadcast message protocol is also possible.

6.4 SPI Registers
There are three registers in the serial peripheral interface which provide control, sta-
tus, and data storage functions. These registers are called the serial peripheral control
register (SPCR), serial peripheral status register (SPSR), and serial peripheral data l/
O register (SPDR) and are described in the following paragraphs.
6.4.1 Serial Peripheral Control Register (SPCR)
SPIE — Serial Peripheral Interrupt Enable
0 = SPIF interrupts disabled
1 = SPI interrupt if SPIF = 1
SPE — Serial Peripheral System Enable
0 = SPI system off
1 = SPI system on
DWOM — Port D Wire-OR Mode Option
DWOM affects all six port D pins together.
0 = Port D outputs are normal CMOS outputs
1 = Port D outputs act as open-drain outputs
