FUNCTIONAL DESCRIPTION

General purpose I/O.

Sink/Source current 4 mA/-100 µA.

Alternate function:

P1.4: HCLAMP (H-clamp pulse) output.

While outputing special function, P1.4's Sink/Source

current is 4 mA/-4 mA.

---------------------------------------------------------

* In the Flash/RAM-test mode

(when the chip is in reset state):

P1.4: A9CTRL input.

General purpose O/P.

Sink/Source current 4 mA/-4 mA.

Alternate function:

P1.5: SOA (Safe Operation Area) outpout.

---------------------------------------------------------

* In the Flash/RAM-test mode

(when the chip is in reset state):

P1.5: A11 input.

* In the functional test mode

(CPU executes out of ext. program memory):

P1.5: doesn't output A11, but functions as

its normal operation.

General purpose I/O.

Sink/Source current 15mA/-100µA.

With slew rate control .

---------------------------------------------------------

* In the Flash/RAM-test mode

(when the chip is in reset state):

P2.0−P2.1: D0−D1 data inputs/outputs.

* In the functional test mode

(CPU executes out of ext. program memory):

P2.0−P2.1: D0−D1 program inputs.
