In H8S/2140B Group compatible vector mode, interrupt input from the IRQ7 pin is ignored when
even one of the KMIMR15 to KMIMR8 bits is cleared to 0. If the KIN7 to KIN0 pins or KIN15 to
KIN8 pins are specified to be used as key-sensing interrupt input pins and wake-up event interrupt
input pins, the interrupt sensing condition for the corresponding interrupt source (IRQ6 or IRQ7)
must be set to low-level sensing or falling-edge sensing. Note that interrupt input cannot be made
from the ExIRQ6 pin.

Note: The ISS7 bit is an external interrupt pin switch bit. For details, see section 6.3.7,

Figure 6.3 Relation between IRQ7 and IRQ6 Interrupts, KIN15 to KIN0 Interrupts,
In extended vector mode, the initial value of the KMIMR6 bit is 1. Accordingly, it does not enable
of disable the IRQ6 pin interrupt. The interrupt input from the ExIRQ6 pin becomes the IRQ6
interrupt request.
