These are 6-bit I/O ports. Besides serving as I/O ports, they function as serial interface data I/O and clock I/O.
The following operating modes can be specified in 1-bit units.
These are 7-bit I/O ports. Besides serving as I/O ports, they function as data I/O and clock I/O of serial interface
P30 to P33 can drive LEDs directly.
The following operating modes can be specified in 1-bit units.
(a) SI30 and SO30
(b) SCK30
(c) R
(d) ASCK0
(a) SDA0
(b) SCL0
These ports function as 6-bit I/O ports. They can be specified as input or output ports in 1-bit units with port mode
register 2 (PM2). On-chip pull-up resistors can be used by setting pull-up resistor option register 2 (PU2).
These ports function as data I/O and clock I/O of serial interface SIO30 or UART0.
These ports function as 7-bit I/O ports. They can be specified as input or output ports in 1-bit units with port mode
register 3 (PM3). P30 to P33 are N-ch open-drain I/O port. Mask ROM version can contain pull-up resistors
in P30 and P31 with the mask option. On-chip pull-up resistors of P34 to P36 can be used by setting pull-up
resistor option register 3 (PU3).
These ports function as data I/O and clock I/O of serial interface IIC0.
Serial data I/O pins of serial interface SIO30.
Serial clock I/O pin of serial interface SIO30.
Serial data I/O pins of serial interface UART0.
Serial clock input pin of serial interface UART0.
Serial data I/O pin of serial interface IIC0.
Serial clock I/O pin of serial interface IIC0.
