6.3.6
Port F pins are general-purpose I/O pins. Parallel I/O function is controlled by the port F data (PTFD) and
data direction (PTFDD) registers which are located in page zero register space. The pin control registers,
pullup enable (PTFPE), slew rate control (PTFSE), and drive strength select (PTFDS) are located in the
high page registers. Refer to
general-purpose I/O control and
Port F general-purpose I/O is shared with TPM1 and TPM2 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.
Refer to
channel pins.
6.3.7
Port G pins are general-purpose I/O pins. Parallel I/O function is controlled by the port G data (PTGD) and
data direction (PTGDD) registers which are located in page zero register space. The pin control registers,
pullup enable (PTGPE), slew rate control (PTGSE), and drive strength select (PTGDS) are located in the
high page registers. Refer to
general-purpose I/O control and
Port G general-purpose I/O is shared with KBI, XTAL, and EXTAL. When a pin is enabled as a KBI input,
the pin functions as an input regardless of the state of the associated PTG data direction register bit. When
