16.6 Reset
Conditions
The range of initialization caused by a system reset, a software reset controlled by the SRES bit in
CCR1, or an abort is shown in table 16.6.

16.7 Interrupt
Sources
The CIR has six interrupt source flags for this LSI. Setting the corresponding enable bit to 1
enables the relevant interrupt request to be issued. Since the six interrupt requests are allocated to
one vector address, it is necessary for the CPU to check the interrupt request flags in order to
determine which interrupt source has caused the interrupt to be requested.
