4.2.11 Port 12
using port mode register 12 (PM12). When used as an input port, use of an on-chip pull-up resistor can be specified
by pull-up resistor option register 12 (PU12).
connecting resonator for main system clock, connecting resonator for subsystem clock, and external clock input for
main system clock.
Caution The function setting on P121 to P124 is available only once after the reset release. The port once
P120 is a 1-bit I/O port with an output latch. Port 12 can be set to the input mode or output mode in 1-bit units
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 4-29 to 4-31 show block diagrams of port 12.
