Freescale Semiconductor, Inc.
The SLOWD6 and SLOWD7 bits enable the slow-edge, open-drain,
high current output (25mA sink) of port pins PTD6 and PTD7
respectively. DDRDx bit is not affected by SLOWDx.
The PTDPU6 and PTDPU7 bits enable the pull-up device on PTD6
and PTD7 respectively, regardless the status of DDRDx bit.
For More Information On This Product,
1 = Slow edge enabled; pin is open-drain output
0 = Slow edge disabled; pin is push-pull (standard I/O)
1 = Enable pull-up device
0 = Disable pull-up device
