Pin function
If the pin is floating, external noise causes the current drain to increase.
The output pins remain in the state in
which they were when the HALT
instruction was executed. If the IDCEN
flag is set, the current drain increases.
It is necessary to take the same cautions
as for the general-purpose output port.
The pin becomes floating.
The current drain varies with the
waveform of the oscillation output of the
clock oscillator.
The larger the amplitude, the current drain
becomes lower.
The oscillation amplitude of the oscillator
varies depending on its crystal and load
capacitance; evaluation is required.
The IDC is disabled.
Each pin behaves as follows:
The current drain will not increase,
even if the RED, GREEN, and BLUE
pins output a low level, or the HSYNC
and VSYNC pins are floating.
All pins output a low level.
The XIN pin is internally pulled
down, and the XOUT pin outputs a
high level.
