General Description
Port B I/O pins
(PTB7/ATD7ÐPTB0/
ATD0)
Port B is an 8-bit special function port that shares all eight pins with the
analog to digital convertor (ADC). See
Analog-to-Digital Converter (ADC) on page 307 and I/O Ports on page
327.
Port C I/O pins
(PTC5ÐPTC0)
PTC5–PTC3 and PTC1–PTC0 are general-purpose bidirectional I/O
port pins. PTC2/MCLK is a special function port that shares its pin with
the system clock. See I/O Ports on page 327.
Port D I/O pins
(PTD7ÐPTD0)
Port D is an 8-bit special function port that shares two of its pins with the
timer interface modules (TIMA and TIMB). see
Timer Interface Module A (TIMA) on page 251 and
Timer Interface Module B (TIMB) on page 277. PTD6–PTD0 also
share pins with the analog to digital convertor (ADC) like port A if the
15-channel ADC is selected.
Port E I/O pins
(PTE7/SPSCKÐPTE0/
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
Serial Communications Interface Module (SCI) on page 179,
Serial Peripheral Interface Module (SPI) on page 217,
Timer Interface Module A (TIMA) on page 251 and I/O Ports on page
327.
Port F I/O pins
(PTF6ÐPTF0/TACH2)
Port F is a 7-bit special function port that shares four of its pins with the
timer interface modules. SeeTimer Interface Module A (TIMA) on
page 251, Timer Interface Module B (TIMB) on page 277 and I/O
Ports on page 327.
Port G I/O pins
(PTG2/KBD2ÐPTG0
/KBD0)
PTG2/KBD2–PTG0/KBD0 are general-purpose bidirectional I/O pins
with Key Wakeup feature. See Keyboard Module (KB) on page 319
and I/O Ports on page 327.
