17. Interrupt during Module Stop Mode
18. Assignment and Selection of Register Addresses
SDA
SCL
BC2 to BC0
IRIC (operation
example)
If clearing of the IRIC flag is delayed due to interrupt handling or the like and the BC counter
value is 1 or 0, confirm that the SCL pin signal is low level after the BC2 to BC0 counter value
has reached 0 before clearing the IRIC flag. (See figure 14.28.)
When the module is stopped in the state that an interrupt is requested, the interrupt source of
the CPU or activation source of the DTC * is not cleared. Be sure to enter module stop mode by
disabling the interrupt beforehand.
Note: * Supported only by the H8S/2268 Group.
Some I
selection is performed by means of the IICE bit in the serial control register X (SCRX). For
details on register addresses, see section 24, List of Registers.

C bus interface registers are assigned to the same address as other registers. Register
