R40: Control Port Pad Control 0, 16,431 (0x402F)
The optional pull-up/pull-down resistors are nominally 250 kΩ. When enabled, these pull-up/pull-down resistors set the control port
signals to a defined state when the signal source becomes three-state.

R41: Control Port Pad Control 1, 16,432 (0x4030)
With IOVDD set to 3.3 V, the low and high drive strengths of the SDA/COUT pin are approximately 2.0 mA and 4.0 mA, respectively.
The high drive strength mode may be useful for generating a stronger ACK pulse in I2C mode, if needed.
