Notes: m1–m4 are the number of states needed for the following memory accesses

m1: SR save (longword write)

m2: PC save (longword write)

m3: Vector address read (longword read)

m4: Fetch of first instruction of interrupt service routine

Icyc: I

Peripheral modules A: DMAC, REF (BSC)

Peripheral modules B: WDT, FRT, TPU, SCIF, SIOF, SIO, E-DMAC
