Hawkins, Nick
Dec. 16, 2022, 6:35 p.m. UTC
From: Nick Hawkins <nick.hawkins@hpe.com>
The GXP SoC supports 10 I2C engines. Each I2C engine is completely
independent and can function both as an I2C master and I2C slave. The
I2C master can operate in a multi master environment. The engines support
a scalable speed from 8kHZ to 1.5 Mhz.
