1.4.11 Port A Input/Output (I/O) Pins (PTA7–PTA0)
PTA7–PTA0 are general-purpose bidirectional I/O port pins. See
1.4.12 Port B I/O Pins (PTB7/ATD7–PTB0/ATD0)
Port B is an 8-bit special function port that shares all eight pins with the Analog-to-Digital Converter (ADC).
See
1.4.13 Port C I/O Pins (PTC5–PTC0)
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 which has a frequency equivalent to the system
clock. See
1.4.14 Port D I/O Pins (PTD7–PTD0/ATD8)
Port D is an 8-bit special-function port that shares seven of its pins with the Analog-to-Digital Converter
module (ADC-15), one of its pins with the Timer Interface Module A (TIMA), and one more of its pins with
the Timer Interface Module B (TIMB). See
Interface Module B
1.4.15 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 A (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
