The RXD/TXD pins are for UART0 function

used.

The SDA/SCK pins are for I

2C function used.

MCLK: EBI clock output pin.

CKO: HCLK clock output

The STADC pin is for ADC external trigger

input.

The CPN1/CPP1 pins are for Comparator1

negative/positive inputs.

The CPO0 pin is the output of Comparator0.

The T0/T1 pins are for Timer0/1 external even

counter input.

The T0EX/T1EX pins are for external

capture/reset trigger input of Timer0/1.

PORT4: Port 4 is an 8-bit four mode output pin

and two mode input. Its multifunction pins are

for /CS, ALE, ICE_CLK and ICE_DAT.

CS for EBI (External Bus Interface) used.

ALE (Address Latch Enable) is used to enable

the address latch that separates the address

from the data on Port 0 and Port 2.
