FT4222_I2CMaster_Init() - which speeds select which modes (SM, FB, FM+ or HS)
« on: September 10, 2019, 04:10:45 PM »
 For FT4222_I2CMaster_Init(), it says:

Quote
This parameter is used to configure the FT4222H to be either SM, FB, FM+ or HS mode.

…and in the API docs:

Quote
Common I²C bus speeds are the 100 kbit/s standard mode (SM), 400 kbit/s fast mode (FM), 1 Mbit/s Fast mode plus (FM+), and 3.4 Mbit/s High Speed mode (HS)

At which kbps values does it switch to the different modes?

When we use 1000 (kbps), our scope shows it's actually running around 750mhz.
