4.4 EIT Processing Mechanism  
The EIT processing mechanism consists of the M32R CPU core and the interrupt controller for internal peripheral I/  
Os. It also has the backup registers for the PC and PSW (the BPC register and the BPSW field of the PSW  
register). The EIT processing mechanism is shown below.
