NOTE:
Additional
Function:
Address:
Port D is an 6-bit general-purpose bidirectional I/O port. These pins are
open-drain when configured as output.
The port D data register contains a data latch for each of the six
port D pins.
Bits 5–1 of PTD are not available in the 32-pin low-profile quad flat pack.
PTD[5:0] — Port D Data Bits
Reset:
Read:
Write:
These read/write bits are software programmable. Data direction of
each port D pin is under control of the corresponding bit in data
direction register D. Reset has no effect on port D data.
The LED direct drive bit, PTDLDD, in the port option control register
(POCR) controls the drive options for PTD5–PTD2 pins. The infrared
LED drive bit, PTDILDD, in the POCR controls the drive options for
PTD1–PTD0 pins. (See
