General Description

1.5.5 External Interrupt Pin (IRQ1)

IRQ1 is an asynchronous external interrupt pin. The IRQ1 pin contains

an internal pullup device. (See Section 14. External Interrupt (IRQ).)

1.5.6 USB Data Pins (D+ and D–)

D+ and D– are the differential data lines used by the USB module. (See

Section 9. Universal Serial Bus Module (USB).)

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

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

Section 12. Input/Output Ports (I/O).) Each pin contains a software

configurable pullup device when the pin is configured as an input. (See

12.8 Port Options.)

1.5.8 Port B (I/O) Pins (PTB7–PTB0)

PTB7–PTB0 are general-purpose bidirectional I/O port pins. (See

Section 12. Input/Output Ports (I/O).) Each pin contains a software

configurable pullup device when the pin is configured as an input. (See

12.8 Port Options.)

1.5.9 Port C I/O Pins (PTC7–PTC0)

PTC7–PTC0 are general-purpose bidirectional I/O port pins. (See

Section 12. Input/Output Ports (I/O).) Port C pins are software

configurable to be LED direct drive ports. Each pin contains a software

configurable pullup device when the pin is configured as an input. (See

12.8 Port Options.)

NOTE:

On the 42-lead SDIP package the PTC7–PTC5 pads are not bonded

out. Set these ports to output to avoid floating inputs.
