e5500 core document

[love_hate_and_repeat]

I'm looking at the e5500 core reference manual for the definitions of some bits but there are no definitions of bits in the e5500 Core Reference Manual and some bits of some registers are also not defined.

For Instance, In the above picture, there are no lower 32-bits of the machine state register. 

I believe The bits of the registers should be defined in the e5500 core reference manual because those registers belong to the e5500 core. am I wrong?

where can I find the definitions of some register bits of the e5500 core If they didn't define in the e5500 core reference manual?

MSR is a 32-bit register, all its bits are shown in the Manual. This applies to other core's Special-Purpose Registers (SPRs).

Note that 64-bit PowerPC architecture is back compatible with 32-bit one, thus notation of the SPRs look like registers are 64-bit ones, however in fact only 32 bits are significant as shown in the description.
