17.6 Port D
17.6.1 Port D Data Register (PTD)

Freescale Semiconductor
Additional Functions:
Alternative Function:
Rev. 1.1
Address:
Port D is an 8-bit special function port that shares two of its pins with the
timer interface module (see
(TIMA)
port D pin has 15mA current drive (sink) and programmable pullup.
The port D data register contains a data latch for each of the eight port D
pins.
PTD[7:0] — Port D Data Bits
TACLK — Timer A Clock Input
TBCLK — Timer B Clock Input
Reset:
Read:
Write:
These read/write bits are software programmable. Data direction of
each port D pin is under the control of the corresponding bit in data
direction register D. Reset has no effect on port D data.
The PTD6 pin becomes TACLK, the timer A (TIMA) external clock
input when the TIMA prescaler select bits, PS[2:0] = 111. See
Section 11. Timer Interface Module A
The PTD4 pin becomes TBCLK, the timer B (TIMB) external clock
input when the TIMB prescaler select bits, PS[2:0] = 111. See
