DIP Switch S3
DIP switch S3 selects the reset configuration source (RST_CFG_SRC) for the MPC8313E.
Figure 27
shows the factory default configuration of S3.
Figure 27. DIP Switch S3
Check the MPC8313E reference manual for the meaning of the CFG_RST_SRC combination. By default,
the DIP switch is set to all ON, meaning CFG_RST_SRC[0..3] = 0000. In this case, the hardware reset
configuration is loaded from local bus NOR flash memory.

DIP Switch S4
DIP switch S4 on the RDB is shown in
Figure 28
, with the factory default configuration.

RSVD is reserved. When software options are implemented, their values can be read from a buffer on the
board. CFG_BOOT_ECC_DIS switch is OFF by default to disable booting with ECC by driving HIGH to
