PowerQUICC II Register Programming
The internal registers of the MPC8272 must be programmed after hard reset as described
in the following sections. The addresses and programming values are in hexadecimal base.
For more information about the this topic in the following sections of this chapter, see the
MPC8272 PowerQUICC II
6.2.1
The power-on reset configuration word is set in the BCSR or Flash or in the E
There are two configuration words: one for the BCSR and Flash (when it is assigned to
CS0) and the other to the E
detailed in Table 6-3 and Table 6-4, respectively.
