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 and KBI. 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 both the ADC and the KBI are configured to use
PTD7 then the pin is controlled by the ADC module.
Refer to
external clock inputs.
Refer to
port D pins as analog inputs.
Refer to
keyboard 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 SCI1, SPI, and TPM1 timer channels. 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.
