Description

DEBUGGER

I/O

Debugging pin.

Should be reserved and tied to high

STEST_RSTN

Chip reset input for test mode. Active low.

Should be reserved and tied to high.

RESETN

Chip reset input. Active low.

Can be tied to high if external reset function is not required.

DCNF0

Device Interface Configuration Selection bit-0 for the HID interface

selection. Refer to Section 5.1

DCNF1

Device Interface Configuration Selection bit-1 for the HID interface

selection. Refer to Section 5.1

VCCIO

P **

+3.3V/2.5V/1.8V supply voltage.

This is the supply voltage for all the I/O ports. This pin shall be

connected to VOUT3V3(pin 22/26) when I/O ports are working at

3.3V

DIO0

( TX_ACTIVE /

TX_LED /

GPIOA

)

I/O

DIO0, Digital Input/Output Pin 0.

This pin can be configured as one of the following three functions via

embedded eFUSE or external EEPROM.

TX_ACTIVE is set as the default function to indicate the UART

transmitting is active.-

TX_LED is set as the LED driving source when data is transmitted on

UART TX port.

GPIOA, General Purpose I/O. GPIOA is another optional function.

DIO1

( GPIOB /

RTSN )

I/O

DIO1, Digital Input/Output Pin 1.

GPIOB, General Purpose I/O. is set as the default function.

RTSN, Request To Send Handshake, can be enabled via a USB

command for the UART interface.

DIO2

( GPIOE /

CTSN )

I/O

DIO2, Digital Input/Output Pin 2.

GPIOE, General Purpose I/O. is set as the default function.

CTSN, Clear To Send Handshake, can be enabled via a USB command

for the UART interface.

DIO3

( RXD /

GPIOC )

I/O

DIO3, Digital Input/Output Pin 3.

RXD, Receive Asynchronous Data Input, is set as default function

when the UART interface is selected via {DCNF1, DCNF0}.

GPIOC, General Purpose I/O, is set as the default function when UART

interface is not configured.

DIO4

( TXD /

GPIOD )

I/O

DIO4, Digital Input/Output Pin 4.

TXD, Transmit Asynchronous Data Output, is set as default when the

UART interface is selected via {DCNF1, DCNF0}.

GPIOD, General Purpose I/O, is set as default when the UART

interface is not configured.

DIO5

I/O

DIO5, Digital Input/Output Pin 5.
