Ports P52–P55 are a 4-bit output port. The output structure is CMOS output.
Pins P52–P55 are also used as OSD output pins R, G, B, OUT1 respectively. The output
structure is CMOS output.
This is a horizontal synchronizing signal input for OSD.
This is a vertical synchronizing signal input for OSD.
This is a 14-bit PWM output pin.
Output
Input
Output
Note 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 “L” 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 swich output structures, set by the following bits.
P30 : bit 0 of port P3 output mode control register
P31 : bit 1 of port P3 output mode control register
When “0,” CMOS output; when “1,” N-channel open-drain output.
3: Only M37221EASP/FP have a built-in D-A converter.
