Register 16433 (0x4031), MCKO Control
Bit 2, MCKO Pin Drive Strength
This bit sets the drive strength of the MCKO 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, MCKO Pull-Up Enable
This bit enables or disables a weak pull-up device on the pad.
The effective resistance of the pull-up is nominally 240 kΩ.
Bit 0, MCKO Pull-Down Enable
This bit enables or disables a weak pull-down device on the pad.
The effective resistance of the pull-down is nominally 240 kΩ.
