tPCI_SYNC_IN
Notes:
1. tPCI_SYNC_IN is the clock period of the input clock applied to PCI_SYNC_IN. When the device is In PCI host mode the primary
clock is applied to the CLKIN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV. See the
MPC8379E Integrated Host Processor Reference Manual for more details.
2. tCLKIN is the clock period of the input clock applied to CLKIN. It is only valid when the device is in PCI host mode. See the
MPC8379E Integrated Host Processor Reference Manual for more details.
3. POR config signals consists of CFG_RESET_SOURCE[0:3], CFG_LBMUX, and CFG_CLKIN_DIV.
