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.

(SOA)
I/O
A11
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.
