Input/Output (I/O) Ports
10.4.3 Port D Control Register (PDCR)
The port D control register enables/disables the pull-up resistor and slow-edge high current capability of
pins PTD6 and PTD7.
SLOWDx — Slow Edge Enable
PTDPUx — Pull-up Enable
112
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 5kΩ pull-up on PTD6 and PTD7 respectively, regardless
the status of DDRDx bit.
1 = Slow edge enabled; pin is open-drain output
0 = Slow edge disabled; pin is push-pull
1 = Enable 5kΩ pull-up
0 = Disable 5kΩ pull-up
Address:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect the input.
