1.4.12 Port D I/O Pins (PTD6/ATD14/TCLKA–PTD0/ATD8)
Port D is a 7-bit special function port that shares all of its pins with the
analog-to-digital converter module (ADC) and one of its pins with the timer
interface module (TIM). (See Section 15. Timer Interface (TIM), Section 3.
Analog-to-Digital Converter (ADC), and Section 11. Input/Output (I/O) Ports.)
1.4.13 Port E I/O Pins (PTE7/SPSCK–PTE0/TxD)
Port E is an 8-bit special function port that shares two of its pins with the timer
interface module (TIM), four of its pins with the serial peripheral interface module
(SPI), and two of its pins with the serial communication interface module (SCI).
(See Section 12. Serial Communications Interface (SCI), Section 14. Serial
Peripheral Interface (SPI), Section 15. Timer Interface (TIM), and Section 11.
Input/Output (I/O) Ports.)
1.4.14 Port F I/O Pins (PTF3/TCH5–PTF0/TCH2)
Port F is a 4-bit special function port that shares all of its pins with the timer
interface module (TIM). (See Section 15. Timer Interface (TIM) and Section 11.
Input/Output (I/O) Ports.)
1.4.15 J1850 Transmit Pin Digital (BDTxD)
BDTxD is a serial digital output data physical interface to the J1850. (See
Section 4. Byte Data Link Controller-Digital (BDLC-D).)
1.4.16 J1850 Receive Pin Digital (BDRxD)
BDRxD is a serial digital input data physical interface from the J1850. (See
Section 4. Byte Data Link Controller-Digital (BDLC-D).
