1.5.12 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 17. Serial Communications
Interface (SCI), Section 18. Serial Peripheral Interface (SPI), Section
16. Timer Interface (TIM), and Section 15. Input/Output (I/O) Ports.)
1.5.13 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 16. Timer Interface (TIM)
and Section 15. Input/Output (I/O) Ports.)
1.5.14 J1850 Transmit Pin Digital (BDTxD)
BDTxD is a serial digital output data physical interface to the J1850. (See
Section 20. Byte Data Link Controller–Digital (BDLC–D).)
1.5.15 J1850 Receive Pin Digital (BDRxD)
BDRxD is a serial digital input data physical interface from the J1850.
(See Section 20. Byte Data Link Controller–Digital (BDLC–D).)
