Register 16432 (0x4030), Communication Port Pad
Control 1
Bit 3, CDATA Pin Drive Strength
This bit sets the drive strength of the CDATA pin. Low mode yields
2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD = 1.8 V.
High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA when
IOVDD = 1.8 V.
Bit 2, CLATCH Pin Drive Strength
This bit sets the drive strength of the CLATCH pin. Low mode
yields 2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD =
1.8 V. High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA
when IOVDD = 1.8 V.

Bit 1, SCL/CCLK Pin Drive Strength
This bit sets the drive strength of the SCL/CCLK pin. Low mode
yields 2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD =
1.8 V. High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA
when IOVDD = 1.8 V.
Bit 0, SDA/COUT Pin Drive Strength
This bit sets the drive strength of the SDA/COUT pin. Low mode
yields 2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD =
1.8 V. High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA
when IOVDD = 1.8 V.
