MPC837xE-RDS Board 2.1 Board-Level Functions The board-level functions discussed in this section are reset, interrupts, clock distribution, and interface specification. 2.1.1 Reset and Reset Configurations The MPC837xE-RDS reset module generates a single reset to reset the MPC837xE and other peripherals on the board. The reset unit provides power-on reset, hard reset, and soft reset signals in compliance with the MPC837xE hardware specification. Figure 2 shows the reset circuitry.

MPC837xE-RDS Board • 2.1.2 The COP/JTAG port also generates the soft reset for the system. Assertion of SRESET causes the MPC837xE to abort all current internal and external transactions and set most registers to their default values. External Interrupts Figure 3 shows the external interrupt circuitry to the MPC837xE.

Clock Distribution Clock Frequency Module Generated by Description 66.666 MHz MPC837xE CLKIN 66.666 MHz oscillator The MPC837xE uses CLKIN to generate the PCI_SYNC_OUT clock signal, which is fed back to the internal system PLL through the PCI_SYNC_IN signal. From the power-on reset configuration, the internal PLL generates the CSB clock, which is fed to the e300 core PLL for generating the e300 core clock.

MPC837xE-RDS Board 2.5.3 Reset Configuration Word The reset configuration word (RCW) controls the clock ratios and other basic device functions, such as PCI host or agent mode, boot location, TSEC modes, and endian mode. The reset configuration word is divided into reset configuration word lower (RCWL) and reset configuration word higher (RCWH) and is loaded from the local bus during the power-on or hard reset flow. The default RCW low-bit setting is 0x0404_0000.
