Setup for SPI Signals

Serial Peripheral Interface (SPI) signals setup consists of connecting the
oscilloscope to a clock, MOSI data, MISO data, and framing signal, then
setting the threshold voltage level for each input channel, and finally
specifying any other signal parameters.

to select the serial slot (Serial 1 or Serial 2) on which the I2C signal is
being decoded.
Missing Acknowledge — finds SDA data is high during any Ack SCL
•
clock bit.
Address with no Ack — finds when the acknowledge of the selected
•
address field is false. The R/W bit is ignored.
Restart — finds when another start condition occurs before a stop

condition.
EEPROM Data Read — finds EEPROM control byte value 1010xxx on the
•
SDA line, followed by a Read bit and an Ack bit. It then looks for the
data value and qualifier set by the Data is softkey and the Data
softkeys.
Frame(Start:Address7:Read:Ack:Data) — finds a read frame on the 17th
•
clock edge if all bits in the pattern match.
Frame(Start:Address7:Write:Ack:Data) — finds a write frame on the 17th
•
clock edge if all bits in the pattern match.
Frame(Start:Address7:Read:Ack:Data:Ack:Data2) — finds a read frame on
•
the 26th clock edge if all bits in the pattern match.
Frame(Start:Address7:Write:Ack:Data:Ack:Data2) — finds a write frame on
•
the 26th clock edge if all bits in the pattern match.
