General Description

1.5.7 External Filter Capacitor Pin (CGMXFC)

CGMXFC is an external filter capacitor connection for the CGM. (See

Section 8. Clock Generator Module (CGM).)

1.5.8 Port A Input/Output (I/O) Pins (PTA7–PTA0)

PTA7–PTA0 are general-purpose bidirectional I/O port pins. (See

Section 15. Input/Output (I/O) Ports.)

1.5.9 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 Section 19. Analog-to-Digital

Converter (ADC) and Section 15. Input/Output (I/O) Ports.)

1.5.10 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. PTC5 is only available with the 64-pin QFP package.

(See Section 15. Input/Output (I/O) Ports.)

1.5.11 Port D I/O Pins (PTD7/ATD15–PTD0/ATD8)

Port D is a 8-bit special function port that shares all of its pins with the

analog-to-digital converter module (ADC) and one of its pins with the

timer interface module (TIM). PTD7/ATD15 is only available with the

64-pin QFP package. (See Section 16. Timer Interface (TIM), Section

19. Analog-to-Digital Converter (ADC), and

Section 15. Input/Output (I/O) Ports.).
