The LBC address/data bus inputs, shown in
configuration register defined in
(GPPORCR).”
LAD[0:31] during POR is captured and stored (read only) in the GPPORCR. Software can then use this
value to inform the operating system about initial system configuration. Typical interpretations include
circuit board type, board ID number, or a list of available peripherals.
4.4.3.25
These POR configuration inputs may be used in the future to control functionality. It is advised
that boards are built with the ability to pull up or pull down these pins. Note that the value latched
on these signals during POR are accessible through the PORDEVSR2, described in
Section 23.4.1.6, “POR Device Status Register 2
4.4.4
The following paragraphs describe the clocking within the device.
4.4.4.1
The MPC8536E takes a single input clock, SYSCLK, as its primary clock source for the e500 core and all
of the devices and interfaces that operate synchronously with the core. As shown in
SYSCLK input (frequency) is multiplied up using a phase lock loop (PLL) to create the core complex bus
(CCB) clock (also called the platform clock). The CCB clock is used by virtually all of the synchronous
system logic, including the L2 cache, and other internal blocks such as the DMA and interrupt controller.
The CCB clock also feeds the PLL in the e500 core and the PLL that create clocks for the local bus memory
controller.
The PCI interface may use SYSCLK as the PCI clock and thus have PCI operation be synchronous with the
platform. Alternately, a separate, independent clock may be used for the PCI interface, in which case PCI
