Reset, Clocking, and Initialization
4.4.3.7
The CPU boot configuration input, shown in
is sampled low at reset, the e500 core is prevented from fetching boot code until configuration by an
external master is complete. The external master frees the CPU to boot by setting EEBPCR[CPU_EN] in
the ECM CCB port configuration register (EEBPCR). See
Register (EEBPCR),”
Note that the value latched on this signal during POR is accessible through the memory-mapped
PORBMSR (POR boot mode status register) described in
Register (PORBMSR).”
Note also that the value latched on this signal during POR affects the PCI agent lock mode (See
