DWOM — Port D Wire-OR Mode Option
This read/write bit disables the high side driver transistors on port D
outputs so that port D outputs become open-drain drivers. DWOM
affects all seven port D pins together.
1 = Port D outputs act as open-drain outputs.
0 = Port D outputs are normal CMOS outputs.
MSTR — Master Mode Select
This read/write bit selects master mode operation or slave mode
operation. Reset clears the MSTR bit.
1 = Master mode
0 = Slave mode
CPOL — Clock Polarity
When the clock polarity bit is cleared and data is not being
transferred, a steady state low value is produced at the SCK pin of the
master device. Conversely, if this bit is set, the SCK pin will idle high.
This bit is also used in conjunction with the clock phase control bit to
produce the desired clock-data relationship between master and
slave. See
Figure 10-1
.
CPHA — Clock Phase
The clock phase bit, in conjunction with the CPOL bit, controls the
clock-data relationship between master and slave. The CPOL bit can
be thought of as simply inserting an inverter in series with the SCK
line. The CPHA bit selects one of two fundamentally different clocking
protocols. When CPHA = 0, the shift clock is the OR of SCK with SS.
As soon as SS goes low, the transaction begins and the first edge on
SCK invokes the first data sample. When CPHA=1, the SS pin may
be thought of as a simple output enable control. See
Figure 10-1
.
SPR1 and SPR0 — SPI Clock Rate Selects
These read/write bits select one of four master mode serial clock
rates, as shown in
Table 10-1
. They have no effect in the slave mode.
