I/O PORT3: Port 3 is an 8-bit four mode output pin
and two mode input. Its multifunction pins are
I/O _{for RXD, TXD, INT0 , INT1, T0, T1, WR ,}
I/O ^{and RD .}
The RXD/TXD pins are for UART0 function
used.
I/O _{The SDA/SCK pins are for I}²_{C function used.}
MCLK: EBI clock output pin.
I/O _{CKO: HCLK clock output}
The STADC pin is for ADC external trigger
I/O _input.
The CPN1/CPP1 pins are for Comparator1
I/O ^{negative/positive inputs.}
The CPO0 pin is the output of Comparator0.
The T0/T1 pins are for Timer0/1 external even
counter input.
I/O
The T0EX/T1EX pins are for external
capture/reset trigger input of Timer0/1.

I/O 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.
I/O
CS for EBI (External Bus Interface) used.
I/O
ALE (Address Latch Enable) is used to enable
the address latch that separates the address
I/O from the data on Port 0 and Port 2.
The ICE_CLK/ICE_DAT pins are for JTAG-ICE
I/O ^{function used.}
PWM0-3 can be used from P4.0-P4.3 when
I/O ^{EBI is active.}
The T2EX/T3EX pins are for external
I/O ^{capture/reset trigger input of Timer2/3.}
