(Rev. 0.9)

USBADR (r/w) :USB device address and enable.

ENUSB = 1 → Enable USB function, clear while chip reset.

USBadr :

USB device address, clear while chip reset or USB bus reset.

INTFLG0 (w) : Interrupt flag. A interrupt event will set its individual flag, and, if the corresponding interrupt

enable bit is set, the 8051’s INT0 source will be driven by a zero level. Software MUST clear

this register while serve the interrupt routine.

RC0I = 1 → No action.

= 0 → Clear RC0I flag.

TX0I = 1 → No action.

= 0 → Clear TX0I flag.

TX1I = 1 → No action.

= 0 → Clear TX1I flag.

TX2I = 1 → No action.

= 0 → Clear TX2I flag.

RstI = 1 → No action.

= 0 → Clear RstI flag.

SusI = 1 → No action.

= 0 → Clear SusI flag.

INTFLG0 (r) :

RC0I

TX0I

TX1I

TX2I

RstI

SusI

Interrupt flag.

= 1 → Endpoint 0 has completed a receive transfer and save the data in RC0FIFO.

= 1 → Endpoint 0 has completed a transmit transfer and empty TX0FIFO.

= 1 → Endpoint 1 has completed a transmit transfer and empty TX1FIFO.

= 1 → Endpoint 2 has completed a transmit transfer and empty TX2FIFO.

= 1 → Indicates the USB bus reset condition.

= 1 → Indicates the USB bus suspend request (no bus activity for 3ms).

INTEN0 (w) : Interrupt enable.

RC0IE = 1 → Enable RC0I interrupt.

TX0IE = 1 → Enable TX0I interrupt.

TX1IE = 1 → Enable TX1I interrupt.

TX2IE = 1 → Enable TX2I interrupt.

RstIE = 1 → Enable RstI interrupt.

SusIE = 1 → Enable SusI interrupt.

INTFLG1 (w) : Interrupt flag. A interrupt event will set its individual flag, and, if the corresponding interrupt

enable bit is set, the 8051’s INT1 source will be driven by a zero level. Software MUST clear

this register while serve the interrupt routine.

RsmI = 1 → No action.

= 0 → Clear RsmI flag.

KbdI = 1 → No action.

= 0 → Clear KbdI flag.

MsI = 1 → No action.

= 0 → Clear MsI flag.

INTFLG1 (r) :

RsmI

KbdI

MsI

Interrupt flag.

= 1 → Indicates the USB bus RESUME condition in suspend mode.

= 1 → Indicates a low input has been detected on anyone of the KSI pins.

= 1 → Indicates a low input has been detected on the MSCLK pin.

INTEN1 (w) : Interrupt enable.

PS2KB = 1 → Enable the pull up resistors on DP/PS2CLK and DM/PS2DATA pins.

FclkE = 1 → Enable the CPU’s faster clock, MUST be cleared before power-down.
