General Description
1.6.14 Port D I/O Pins (PTD7–PTD0)
PTD7–PTD0 are general-purpose bidirectional I/O port pins. PTD6 and
PTD4 are special function port pins that are shared with the timer
interface modules (TIMA and TIMB). See Section 11. Timer Interface
Module A (TIMA) and Section 12. Timer Interface Module B (TIMB).
1.6.15 Port E I/O Pins (PTE7/SPSCK–PTE0/TxD)
PTE7–PTE0 are special function, bidirectional port pins. PTE7–PTE4
are shared with the serial peripheral interface mode (SPI), PTE3–PTE2
are shared with timer A (TIMA), and PTE1–PTE0 are shared with the
serial communications interface (SCI). See Section 15. Serial
Communications Interface Module (SCI), Section 16. Serial
Peripheral Interface Module (SPI), Section 11. Timer Interface
Module A (TIMA), and Section 17. Input/Output (I/O) Ports.
1.6.16 Port F I/O Pins (PTF7–PTF0/TACH2)
PTF7–PTF6 are general-purpose bidirectional I/O port pins.
PTF5–PTF0 are special function, bidirectional port pins. PTF5–PTF2 are
shared with timer B (TIMB), and PTF1–PTF0 are shared with timer A
(TIMA). See Section 11. Timer Interface Module A (TIMA), Section
12. Timer Interface Module B (TIMB), and Section 17. Input/Output
(I/O) Ports.
1.6.17 Port G I/O Pins (PTG2/KBD2–PTG0/KBD0)
PTG2–PTG0 are general-purpose bidirectional I/O pins with keyboard
wakeup function. See Section 19. Keyboard Interrupt Module (KBI)
and Section 17. Input/Output (I/O) Ports.
1.6.18 Port H I/O Pins (PTH1/KBD4–PTH0/KBD3)
PTH1–PTH0 are general-purpose bidirectional I/O pins with Keyboard
wakeup function. See Section 19. Keyboard Interrupt Module (KBI)
and Section 17. Input/Output (I/O) Ports.
