17.6.3 Port D Input Pullup Enable Register (PTDPUE)
MC68HC908AB32
MOTOROLA
—
Rev. 1.0
Address:
When DDRDx is a logic 1, reading address $0003 reads the PTDx data
latch. When DDRDx is a logic 0, reading address $0003 reads the
voltage level on the pin. The data latch can always be written, regardless
of the state of its data direction bit.
Table 17-5
The port D input pullup enable register (PTDPUE) controls the input
pullup device for each of the eight port D pins. Each bit is individually
configurable and requires that the data direction register, DDRD, bit be
configured as an input. Each pullup is automatically and dynamically
disabled when a port bit’s DDRD is configured for output mode.
PTDPUE[7:0] — Port D Input Pullup Enable Bits
Notes:
Reset:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect the input.
