P30 (INT3/RXIN)
I/O (Input)
6-bit programmable input/output port.
Each bit of these ports can be
individually configured as an input or
an output under software control.
During reset, all bits are configured as
inputs. When used as a serial bus
interface input/output, the latch must
be set to “1”.

P40 ( PWM0 )
I/O (Output)
8-bit programmable input/output port.
Each bit of these ports can be
individually configured as an input or
an output under software control.
During reset, all bits are configured as
inputs. When used as a PWM output,
the latch must be set to “1”.

I/O
(Output/Input /Input)
8-bit programmable input/output port.
Each bit of these ports can be
individually configured as an input or
an output under software control.
During reset, all bits are configured as
inputs. When used as a PWM output, a
serial bus interface input/output, the
latch must be set to “1”.

( KWU4 /YBLIN/AIN4)
I/O (Input)
8-bit programmable input/output port.
(P67 to P64: Tri-State, P63 to P60:
High current output) Each bit of these
ports can be individually configured as
an input or an output under software
control. During reset, all bits are
configured as inputs. When used P64
to P67 as port, each bit of the P6 port
data selection register (Bit7 to 4 in
ORP6S) must be set to “1”.
