SYStem.Option.HRCWOVerRide Override HRCW on SYStem.Up
MPC83XX and MPC512X only. Override the HRCW on SYStem.Up via JTAG. To disable this system option,
call without parameter. This command is usually required to connect to a processor with erased/empty flash
(HRCW not set).
Usage:
SYStem.Option.ICFLUSH Invalidate instruction cache before go/step
Format: SYStem.Option.HRCWOVerRide <value>
<value> Hard reset configuration word (64 bit) in the order
0xHHHHHHHHLLLLLLLL
NOTE:
• The CPU will remember and use the overridden HRCW until the next
power cycle or power-on reset.
• If JTAG_HRESET is connected to CPU_PORESET,
SYStem.Option.HRCWOVerRide will only work in conjunction with
SYStem.Option.ResetMode JTAG_HRST.
