configitem Target Speed
value
Target Speed selects the target clock speed of the SPI.
The Target Speed may be lowered to the closest Operating Speed capability of the device. If so, a
warning will be noted.
0 or clearing the selection selects the minimum speed.
Target Speed has units of Hz.
Blank the value for "<Minimum>".
configitem Idle Clock Level
value
Idle Clock Level, also known as Clock Polarity or CPOL, selects the level of the clock when idle:
Low means the idle clock is at a low level. This is equivalent to CPOL=0.
High means the idle clock is at a high level. This is equivalent to CPOL=1.
Idle Clock Level may be "Low" or "High".
configitem Clock Edge
value
Clock Edge, also known as Clock Phase or CPHA, selects the clock edge for latching data:
First means each bit is latched on the first edge of the clock. This is equivalent to CPHA=0. When Idle
Clock Level is Low, data is latched on the rising edge. When Idle Clock Level is High, data is latched on
the falling edge.
Second means each bit is latched on the second edge of the clock. This is equivalent to CPHA=1. When
Idle Clock Level is Low, data is latched on the falling edge. When Idle Clock Level is High, data is
latched on the rising edge.
Clock Edge may be "First" or "Second".
configitem Bits Per Word
value
Bits Per Word selects the number of bits per word of transfer.
Bits Per Word may be "8" or "16".
configitem First Transfer
