Furthermore, the data output of the serial interface can be assigned to P120 of the 78K0/KC2-L by setting the port
P120 functions as an I/O port. P121 to P125 function as an Input port. These pins also function as pins for
Set bit 5 (RSTM) of the reset pin mode register (RSTMASK) to 1 when using P125/RESET as an input port, and
The following operation modes can be specified in 1-bit units.
P70 to P75 function as an I/O port. P70 to P75 can be set to input or output port in 1-bit units using port mode
register 7 (PM7). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 7 (PU7).
P70 to P75 function as key interrupt input pins.
(a) KR0 to KR5
P120 to P125 function as an I/O port. P120 to P125 can be set to input or output port using port mode register 12
(PM12). Only for P120 and P125, use of an on-chip pull-up resistor can be specified by pull-up resistor option
register 12 (PU12).
P120 to P125 function as pins for external interrupt request input, potential input for external low-voltage
detection, connecting resonator for main system clock, connecting resonator for subsystem clock, external clock
input for main system clock, external clock input for subsystem clock, external reset input, and clock input and
data I/O for flash memory programmer/on-chip debugger.
