Input/Output (I/O) Ports (PORTS)
PTCPUE6–PTCPUE0 — Port C Input Pullup Enable Bits
12.5 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 two timer interface (TIM1 and TIM2) modules. Port D also has software
configurable pullup devices if configured as an input port.
12.5.1 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
T1CH1 and T1CH0 — Timer 1 Channel I/O Bits
SPSCK — SPI Serial Clock
MOSI — Master Out/Slave In
MISO — Master In/Slave Out

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
The PTD7/T1CH1–PTD6/T1CH0 pins are the TIM1 input capture/output compare pins. The edge/level
select bits, ELSxB and ELSxA, determine whether the PTD7/T1CH1–PTD6/T1CH0 pins are timer
channel I/O pins or general-purpose I/O pins. See
The PTD3/SPSCK pin is the serial clock input of the SPI module. When the SPE bit is clear, the
PTD3/SPSCK pin is available for general-purpose I/O.
The PTD2/MOSI pin is the master out/slave in terminal of the SPI module. When the SPE bit is clear,
the PTD2/MOSI pin is available for general-purpose I/O.
The PTD1/MISO pin is the master in/slave out terminal of the SPI module. When the SPI enable bit,
SPE, is clear, the SPI module is disabled, and the PTD0/SS pin is available for general-purpose I/O.
1 = Corresponding port C pin configured to have internal pullup
0 = Corresponding port C pin internal pullup disconnected
