General Description
(SPI), and two of its pins with the serial communication interface module (SCI).
(See Section 13. Serial Communications Interface (SCI), Section 15. Serial
Peripheral Interface (SPI), Section 16. Timer Interface (TIM), and Section 12.
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 16. Timer Interface (TIM) and Section 12.
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).)
