Watchdog reset at board reset [Y/N] = N?
This parameter controls whether or not the watchdog timer is to be
reset by the
<PPC1BUG>
. If the value of this parameter is Y (yes), then
the watchdog timer will be reset. If it is N (no), then it will not be reset.
The ramifications of not resetting the watchdog timer are that if some
process (the Operating System, for example) has turned on the
watchdog and fails to reset it before terminating, then there is a chance
the timer will go off during system boot and cause the system to reset
again. (Default = N)
Memory Size Enable [Y/N] = Y?
Memory Size Starting Address = 00000000?
The default Starting Address is $00000000.
Memory Size Ending Address = 02000000?
The default Ending Address is the calculated size of local memory. If
the memory start is changed from $00000000, this value will also need
to be adjusted.
DRAM Speed in NANO Seconds = 60?
The default setting for this parameter will vary depending on the speed
of the DRAM memory parts installed on the board. The default is set
to the slowest speed found on the available banks of DRAM memory.
ROM First Access Length (0 - 31) = 10?
This is the value programmed into the MPC105 ROMFAL field
(Memory Control Configuration Register 8: bits 23-27) to indicate the
number of clock cycles used in accessing the ROM. The lowest
allowable ROMFAL setting is $00; the highest allowable is $1F. The
value to enter depends on processor speed; refer to your
Y
Memory will be sized for Self Test diagnostics
(Default).
N
Memory will not be sized for Self Test diagnostics.
