Tool/software:
Hello expert,
The CC3135MOD datasheet has a HOST SPI timing chart.
Please tell me about it.
Q1. Am I correct in the following recognition?
[Master = MCU Slave = CC3135MOD]
Q2. Are MOSI and MISO inverted?
If Q1. is correct, setup time(T6) and hold time(T7) would be the parameters to be adapted to MOSI.
Regards,
Ryoma
Greetings,
it is correct to assume "Master" is the host MCU, and the other to be the CC3135 device. I would recommend you refer to our SimpleLink Wi-Fi® CC3x20, CC3x3x Network Processor User Guide (Lit# swru455) for more explanation on the SPI.

Hi Jessica,
Thank you for your reply.
I understand Q1.
Q2. Are MOSI and MISO inverted?
Regarding Q2, is it correct that MISO and MOSI are not inverted in the case of the timing chart from the CC3135 perspective?
Q3. MISO waveform
Additionally, I would like your opinion on the MISO waveform.
Is there a problem with a gradual decrease in the MISO waveform as shown in the figure below?
[Range：5 us]
[Range：500 ns]
※CH1：CS, CH2：Clock, CH3：MOSI, CH4：MISO
Regards,
Ryoma
