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.
With IOVDD set to 1.8 V, the low and high drive strengths are approximately 0.8 mA and 1.7 mA, respectively. The high drive strength
mode may be useful for generating a stronger ACK pulse in I
