P63 pin is also used as OSD clock input pin OSC1. P64 pin is also used as OSD clock output pin OSC2. The output structure is CMOS output. P64 pin is also used as sub-clock output pin XCOUT. The output structure is CMOS output. P63 pin is also used as sub-clock input pin XCIN. Input composite video signal through a capacitor. Connect a capacitor between VHOLD and VSS. Connect a resistor between RVCO and VSS. Connect a filter using of a capacitor and a resistor between HLF and VSS. This is a horizontal synchronizing signal input for OSD. This is a vertical synchronizing signal input for OSD. Note : As shown in the memory map (Figure 3), port P0 is accessed as a memory at address 00C016 of zero page. Port P0 has the port P0 direction register (address 00C116 of zero page) 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. |
