21.5.6. RAM Check March-C Start Command
"RAM Check March-C Start" command can be set under "mc_state_idle" state.
"RAM Check March-C Start" command starts RAM March-C check, the state is moved to
"mc_state_ram_march_c" after the memory check start..
After finishing the memory check, HW Processor makes an interrupt on default and goes to
"mc_state_idle". Please check PROCESSING bit field in STATUS register, it shows OK or ERROR after
check, if ERROR is occurred, please check RESULT register, it shows first fail address.
When state transition is occurred, HW Processor makes an interrupt on default, the interrupt can be
masked by
INTMASK on
