G2 core reference manual says:
Features specific to the G2 core not present on the original MPC603e
(PID6-603e) processors follow:
...
Enhanced debug features
— Addition of three breakpoint registers—IABR2, DABR, and DABR2
— Two new breakpoint control registers—DBCR and IBCR
e500 has DAC1 and DAC2 instead for breakpoints iaw e500 core reference
manual.
