Mask-Options of V850/Fx3, Cargate

The mask options require a special handling. In normal operation mode the mask option values are located

in flash memory at address 0x7A, 0x7B. In emulation mode these values have to be copied to a certain

debug register EMUMO at address 0xFFFFF9FA.

• the value of address 0x7A has to be copied to the low byte of EMUMO

• the value of address 0x7B has to be copied to the high byte of EMUMO

The new options become active at the next SYStem.UP.

Add following startup sequence to your script:

SYStem.Up ; initial startup

disable RomSecurityUnit ; see demo scripts

; set MaskOptions to EMUMO register

Data.Set 0xFFFFF9FA %Word 0x0800

SYStem.Up ; now the MaskOption settings are active

disable RomSecurityUnit ; see demo scripts
