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 (TIMA), 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 16. Serial Communications
Interface Module (SCI)

1.5.13 Port F I/O Pins (PTF6–PTF0/TACH2)
Port F is a 7-bit special function port that shares its pins with the timer
interface module (TIMB) if the part is configured as MC68HC08AZ32
emulator protocol. If the part is configured as MC68HC08AS20 emulator
protocol, four of its pins will be shared with the timer interface module
(TIMA-6). (See
Section 18. Timer Interface (TIMA-4)
or
Section 25.
Timer Interface (TIMA-6)
,
Section 19. Timer Interface (TIMB)
, and
Section 22. MC68HC08AZ32 Emulator Input/Output Ports
or
Section 27. MC68HC08AS20 Emulator Input/Output Ports
depending on your configuration.).
NOTE:
PTF4–PTF6 is available only in 64-pin packages.
1.5.14 Port G I/O Pins (PTG2/KBD2–PTG0/KBD0)
NOTE:
This port is available only in the MC68HC08AZ32 emulator.
Port G is a 3-bit special function port that shares all of its pins with the
keyboard interrupt module (KBD) only if the part is configured as
MC68HC08AZ32 Emulator (64-pin QFP) protocol. If port G is available
