Note
Caution The function setting on P121 to P124 is available only once after the reset release. The port once
P120 is I/O port with an output latch. Port 12 can be set to the input mode or output mode in 1-bit units using port
P121 to P124 are 4-bit input ports.
This port can also be used for external interrupt request input, potential input for external low-voltage detection,
Reset signal generation sets port 12 to input mode.
Figures 4-23 to 4-25 show block diagrams of port 12.
INTP4 and INTP5 are shared with P70 and P71, respectively, in products other than the 78K0R/IB3 and the
38-pin products of the 78K0R/IC3.
set for connection to an oscillator cannot be used as an input port unless the reset is performed.
