Input/Output (I/O) Ports
13.5.3 Port C Input Pullup Enable Register
The port C input pullup enable register (PTCPUE) contains a software configurable pullup device for each
of the seven port C pins. Each bit is individually configurable and requires that the data direction register,
DDRC, bit be configured as an input. Each pullup is automatically and dynamically disabled when a port
bit’s DDRC is configured for output mode.
PTCPUE6–PTCPUE0 — Port C Input Pullup Enable Bits
13.6 Port D
Port D is an 8-bit special-function port that shares four of its pins with the serial peripheral interface (SPI)
module and four of its pins with the two timer interface (TIM1 and TIM2) modules. Port D also has software
configurable pullup devices if configured as an input port.
13.6.1 Port D Data Register
The port D data register (PTD) contains a data latch for each of the eight port D pins.
PTD7–PTD0 — Port D Data Bits
T2CH1 and T2CH0 — Timer 2 Channel I/O Bits

These writable bits are software programmable to enable pullup devices on an input port bit.
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 PTD7/T2CH1–PTD6/T2CH0 pins are the TIM2 input capture/output compare pins. The edge/level
select bits, ELSxB:ELSxA, determine whether the PTD7/T2CH1–PTD6/T2CH0 pins are timer channel
I/O pins or general-purpose I/O pins. See
1 = Corresponding port C pin configured to have internal pullup
0 = Corresponding port C pin internal pullup disconnected
