Port 5

8-bit

input-only

port

with

Schmitt-Trigger

characteristics. The pins of Port 5 also serve as the (up to 8)

analog input channels for the A/D converter, where P5.x

equals ANx (Analog input channel x).

The following pins of Port 5 also serve as timer inputs:

P5.4

T2EUD

GPT1 Timer T2 Ext.Up/Down Ctrl.Input

P5.5

T4EUD

GPT1 Timer T4 Ext.Up/Down Ctrl.Input

P5.6

T2IN

GPT1 Timer T2 Input for

Count/Gate/Reload/Capture

P5.7

T4IN

GPT1 Timer T4 Input for

Count/Gate/Reload/Capture

I/O

Port 3

9-bit

bidirectional

I/O

port. It

is bit-wise

programmable for input or output via direction bits. For a pin

configured as input, the output driver is put into high-

impedance state.

The following Port 3 pins also serve for alternate functions:

P3.4

T3EUD

GPT1 Timer T3 Ext.Up/Down Ctrl.Input

P3.6

T3IN

GPT1 Timer T3 Count/Gate Input

P3.8

MRST

SSC Master-Rec./Slave-Transmit I/O

P3.9

MTSR

SSC Master-Transmit/Slave-Rec. O/I

P3.10

TXD0

ASC0 Clock/Data Output (Asyn./Syn.)

P3.11

RXD0

ASC0 Data Input (Asyn.) or I/O (Syn.)

P3.12

BHE

Ext. Memory High Byte Enable Signal,

WRH

Ext. Memory High Byte Write Strobe

P3.13

SCLK

SSC Master Clock Outp./Slave Cl. Inp.

P3.15

CLKOUT

System Clock Output (=CPU Clock)

Port 4

6-bit

bidirectional

I/O

port. It

is bit-wise

programmable for input or output via direction bits. For a pin

configured as input, the output driver is put into high-

impedance state.

In case of an external bus configuration, Port 4 can be used to

output the segment address lines:

P4.0

A16

Least Significant Segment Addr. Line

CS3

Chip Select 3 Output

...

P4.3

A19

Segment Address Line

CS0

Chip Select 0 Output

P4.5

A20

Segment Address Line,

CAN_RxD CAN Receive Data Input

P4.6

A21

Most Significant Segment Addr. Line,

CAN_TxD CAN Transmit Data Output
