When the IIC module is enabled, PTC2 serves as the IIC modules’s serial data input/output pin (SDA) and

PTC3 serves as the clock pin (SCL). Refer to the Inter-Integrated Circuit (IIC) Module section for more

information about using PTC2 and PTC3 as IIC pins.

8.3.4 Port D, TPM1 and TPM2

Figure 8-5 Port D Pin Names

Port D is an 8-bit port shared with the two TPM modules, TPM1 and TPM2 and general-purpose I/O.

When the TPM1 or TPM2 modules are enabled in output compare or input captures modes of operation,

the pin direction will be controlled by the module function.

Port D pins are available as general-purpose I/O pins controlled by the port D data (PTDD), data direction

(PTDDD), pullup enable (PTDPE), and slew rate control (PTDSE) registers. Refer to 8.4 Parallel I/O

Controls for more information about general-pupose I/O control.

The TPM2 module can be configured to use PTD7–PTD3 as either input capture, output compare, PWM,

or external clock input pins (PTD3 only). Refer to the Timer/PWM (TPM) Module section for more

information about using PTD7–PTD3 as timer pins.

The TPM1 module can be configured to use PTD2–PTD0 as either input capture, output compare, PWM,

or external clock input pins (PTD0 only). Refer to the Timer/PWM (TPM) Module section for more

information about using PTD2–PTD0 as timer pins.

8.3.5 Port E, SCI1, and SPI

Figure 8-6 Port E Pin Names

Port E is an 8-bit port shared with the SCI1 module, SPI module, and general-purpose I/O. When the SCI

or SPI modules are enabled, the pin direction will be controlled by the module function.

Port E pins are available as general-purpose I/O pins controlled by the port E data (PTED), data direction

(PTEDD), pullup enable (PTEPE) and slew rate control (PTESE) registers. Refer to 8.4 Parallel I/O

Controls for more information about general-pupose I/O control.

When the SCI1 module is enabled, PTE0 serves as the SCI1 module’s transmit pin (TxD1) and PTE1

serves as the receive pin (RxD1). Refer to the Serial Communications Interface (SCI) Module section

for more information about using PTE0 and PTE1 as SCI pins.
