I/O

Description

I/O This is an 8-bit I/O port equivalent to P0.

I/O P60 to P63 are I/O ports for UART0.

P64 to P67 are I/O ports for UART1.

These pins can be used for Serial Sound Interface, I2C and SPI communication.

I/O This is an 8-bit I/O port equivalent to P0. P70 and P71 are N-channel open drain

output.

I P70 to P77 are I/O ports for Timer A0 to A3.

O

P70 to P73 are I/O ports for UART2.

I/O P74 to P77 are I/O ports for UART3.

These pins can be used for I 2C and SPI communication.

O These pins are capable of sinking 20mA for driving LEDs.

I/O This is a 7-bit I/O port equivalent to P0.

I P82 to P84 are external interrupt input ports.

I Input port for NMI interrupt.

I, O P86 and P87, connect an oscillator between these pins for sub-clock generation.

I/O This is a 3-bit I/O port equivalent to P0.

I P93 is an A/D trigger input port.

O P90 can be used to attach or detach from the USB host without disconnecting the

USB cable.

O P92 is an output for the USB start of frame signal pulse.

I/O This is an 8-bit I/O port equivalent to P0.

I P100 to P107 are key-input interrupt ports.

I P100 to P107 are analog input ports for A/D converter.
