I/O port P3
Ports P3
0
and P3
1
are a 2-bit I/O port and has basically the same functions as port 0.
The output structure can be selected either CMOS output or N-channel open-drain output
structure. (See notes 1, 3)
Pins P3
0
and P3
1
are also used as analog input pins AD5 and AD6 respectively.
Pin P5
0
and P5
1
are 2-bit input ports.
Pin P5
0
is also used as H
SYNC
input. This is a horizontal synchronous signal input for OSD.
Pin P5
1
is also used as V
SYNC
input. This is a vertical synchronous signal input for OSD.
Ports P5
2
–P5

Notes 1:
Port Pi (i = 0 to 3) has the port Pi direction register which can be used to program each bit as an input (“0”) or an output (“1”). The pins programmed as “1”
in the direction register are output pins. When pins are programmed as “0,” they are input pins. When pins are programmed as output pins, the output data
are written into the port latch and then output. When data is read from the output pins, the output pin level is not read but the data of the port latch is read.
This allows a previously-output value to be read correctly even if the output LOW voltage has risen, for example, because a light emitting diode was directly
driven. The input pins are in the floating state, so the values of the pins can be read. When data is written into the input pin, it is written only into the port
latch, while the pin remains in the floating state.
2:
To switch output functions, set the raster color register and OSD control register. When pins P2
6
and P2
7
are used as the OSD clock input/output pins, set
the corresponding bits of the port P2 direction register to “0” (input mode).
3:
To switch output structures, set bits 2 and 3 of the port P3 direction register, When “0,” CMOS output ; when “1,” N-channel open-drain output.
