Using 64-bit wide ﬂash with MPE60x parts

I am using a MPE60X device which does not have ﬂoating point enabled. Can I use a MPC106

with a 64b wide Flash?

No. Since the ﬂash must be written to with 'full' bus width transactions the only way to accom-

plish this with the PowerPC architecture is to perform a 'stfd' (store ﬂoating point double instruc-

tion). On the MPE devices the ﬂoating point unit is disabled. Therefore, you would not be able to

perform the 64b wide write. The solution to this problem is to use a regular MPC device.
