Notes: m1 to m4 are the number of states needed for the following memory accesses.
m1: Vector address read (longword read)
m2: SR save (longword write)
m3: PC save (longword write)
m4: Banked registers (R0 to R14, GBR, MACH, MACL, and PR) are restored from the
stack.
1. In the case that m1 = m2 = m3 = m4 = 1 Icyc.
2. In the case that (Iφ, Bφ, Pφ) = (200 MHz, 66 MHz, 33 MHz).
