that the application system does not inadvertently stop due to a program loop. A write access to the special registers
is made in a specific sequence, and an illegal store operation is reported to the system status register (SYS).
Special registers are registers that are protected from being written with illegal data due to a program loop.
The V850E/IF3 and V850E/IG3 have the following five special registers.
• Power save control register (PSC)
• Processor clock control register (PCC)
• Reset source flag register (RESF)
• Clock monitor mode register (CLM)
• Low-voltage detection register (LVIM)
In addition, a command register (PRCMD) is provided to protect against a write access to the special registers so
