22.4 Cautions

(1) If a low level is input to any of the KR0 to KR7 pins, the INTKR signal is not generated even if the falling edge
(2) The RXDA1 and KR7 pins must not be used at the same time. When using the RXDA1 pin, do not use the
(3) If the KRM register is changed, an interrupt request signal (INTKR) may be generated. To prevent this,
(4) To use the key interrupt function, be sure to set the function of the port pin to “key return pin” and then enable
is input to another pin.
KR7 pin. When using the KR7 pin, do not use the RXDA1 pin (it is recommended to set the PFC91 bit to 1
and clear PFCE91 bit to 0).
change the KRM register after disabling (DI) or masking interrupts, then clear the interrupt request flag
(KRIC.KRIF bit) to 0, and enable (EI) or unmask interrupts.
the key interrupt function by using the KRM register. To switch the pin function from key return pin to port pin,
disable the key interrupt function by using the KRM register and then set pin function to “port pin”.
