Notes:
After Reset
1. Bits P3_0 to P3_2 and P3_6 in the P3 register are reserved bits. If it is necessary to set bits P3_0 to P3_2 and
2. Bits P4_0 to P4_1 in the P4 register are unavailable on this MCU. If it is necessary to set bits P4_0 to P4_1 set to
Pi_j Bit (i = 1, 3, 4, j = 0 to 7) (Port Pi_j Bit)

0. When read, the content is 0. Bits P4_3, P4_4 are reserved bits. If it is necessary to set bits P4_3 and P4_4, set
to 0. When read, the content is 0.
Data input and output to and from external devices are accomplished by reading and writing to the Pi register.
The Pi register consists of a port latch to retain output data and a circuit to read the pin status. The value written
in the port latch is output from the pin. Each bit in the Pi register corresponds to one port.
The pin level of any I/O port which is set to input mode can be read by reading the corresponding bit in this
register. The pin level of any I/O port which is set to output mode can be controlled by writing to the
corresponding bit in this register.
