15.1
The has an on-chip 8-bit general-purpose I/O port and an on-chip I/O port for the serial
communication interface (SCI).
15.1.1
The general-purpose I/O port has the following features:
The SCI I/O port has the following features:
15.1.2
Figure 15.1 shows a block diagram of the 8-bit general-purpose I/O port.
Direction of each bit of the 8-bit I/O port can be set independently
When each bit is set for input mode, it is possible to set each bit for independent pull-up
Ports can be used as I/O ports or as data bus lines, for a maximum data bus width of 32 bits, by
setting the PORTEN bit in bus control register 2 (BCR2)
When the I/O port is set to output and the SCI is not enabled, data can be output. This allows
transmission of the break status. SCK pin control is also possible.
The value of the RxD pin can be read at any time. This enables break detection.
