6.3.4
Port D pins are general-purpose I/O pins. Parallel I/O function is controlled by the port D data (PTDD) and
data direction (PTDDD) registers which are located in page zero register space. The pin control registers,
pullup enable (PTDPE), slew rate control (PTDSE), and drive strength select (PTDDS) are located in the
high page registers. Refer to
general-purpose I/O control and
Port D general-purpose I/O are shared with the ADC. When any of these shared functions is enabled, the
direction, input or output, is controlled by the shared function and not by the data direction register of the
parallel I/O port. When a pin is shared with both the ADC and a digital peripheral function, the ADC has
higher priority. For example, in the case that the ADC are configured to use PTD3, then the pin is
controlled by the ADC module.
Refer to
port D pins as analog inputs.
6.3.5
Port E pins are general-purpose I/O pins. Parallel I/O function is controlled by the port E data (PTED) and
data direction (PTEDD) registers which are located in page zero register space. The pin control registers,
pullup enable (PTEPE), slew rate control (PTESE), and drive strength select (PTEDS) are located in the
high page registers. Refer to
general-purpose I/O control and
Port E general-purpose I/O is shared with TPM1 timer channels and SCI. When any of these shared
functions is enabled, the direction, input or output, is controlled by the shared function and not by the data
direction register of the parallel I/O port. Also, for pins which are configured as outputs by the shared
function, the output data is controlled by the shared function and not by the port data register.
Refer to
port E pins as SCI pins.
Refer to
channel pins.
