1C

XTALIN

Input

N/A

Crystal Input. Connect this signal to a 24 MHz parallel resonant, funda-

 

 

 

 

mental mode crystal and load capacitor to GND.

 

 

 

 

It is also correct to drive XTALIN with an external 24-MHz square wave

 

 

 

 

derived from another clock source.

2C

XTALOUT

Output

N/A

Crystal Output. Connect this signal to a 24 MHz parallel resonant, funda-

 

 

 

 

mental mode crystal and load capacitor to GND.

 

 

 

 

If an external clock is used to drive XTALIN, leave this pin open.

2B

CLKOUT

O/Z

12 MHz

CLKOUT. 12-, 24- or 48-MHz clock, phase locked to the 24 MHz input

 

 

 

 

clock. The 8051 defaults to 12 MHz operation. The 8051 may tri-state this

 

 

 

 

output by setting CPUCS.1 = 1.

Port A

 

 

 

 

8G

PA0 or

I/O/Z

I

Multiplexed pin whose function is selected by PORTACFG.0

 

INT0#

 

(PA0)

PA0 is a bidirectional IO port pin.

 

 

 

 

INT0# is the active LOW 8051 INT0 interrupt input signal, which is either

 

 

 

 

edge triggered (IT0 = 1) or level triggered (IT0 = 0).

6G

PA1 or

I/O/Z

I

Multiplexed pin whose function is selected by:

 

INT1#

 

(PA1)

PORTACFG.1

 

 

 

 

PA1 is a bidirectional IO port pin.

 

 

 

 

INT1# is the active LOW 8051 INT1 interrupt input signal, which is either

 

 

 

 

edge triggered (IT1 = 1) or level triggered (IT1 = 0).

8F

PA2 or

I/O/Z

I

Multiplexed pin whose function is selected by two bits:

 

SLOE

 

(PA2)

IFCONFIG[1:0].

 

 

 

 

PA2 is a bidirectional IO port pin.

 

 

 

 

SLOE is an input-only output enable with programmable polarity

 

 

 

 

(FIFOPINPOLAR.4) for the slave FIFO’s connected to FD[7:0] or FD[15:0].

7F

PA3 or

I/O/Z

I

Multiplexed pin whose function is selected by:

 

WU2

 

(PA3)

WAKEUP.7 and OEA.3

 

 

 

 

PA3 is a bidirectional IO port pin.

 

 

 

 

WU2 is an alternate source for USB Wakeup, enabled by WU2EN bit

 

 

 

 

(WAKEUP.1) and polarity set by WU2POL (WAKEUP.4). If the 8051 is in

 

 

 

 

suspend and WU2EN = 1, a transition on this pin starts up the oscillator

 

 

 

 

and interrupts the 8051 to allow it to exit the suspend mode. Asserting this

 

 

 

 

pin inhibits the chip from suspending, if WU2EN = 1.

Note

9.Unused inputs must not be left floating. Tie either HIGH or LOW as appropriate. Outputs should only be pulled up or down to ensure signals at power up and in standby. Note also that no pins should be driven while the device is powered down
