After an update to the MX51 reference manual (Rev. 5), the values of the PAD_CTL_DRV_VOT_LOW and PAD_CTL_DRV_VOT_HIGH are now clearly wrong:
"Bit 13: High / Low Output Voltage Range. This bit selects the output voltage mode for SD2_CMD. 0 High output voltage mode 1 Low output voltage mode"
The values are currently negated in code - fixed.
