that the application system does not inadvertently stop due to a program hang-up. 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 hang-up.
The V850ES/SA2 and V850ES/SA3 have the following three special registers.
• Power save control register (PSC)
• Processor clock control register (PCC)
• Watchdog timer mode register (WDTM)
In addition, a command register (PRCDM) is provided to protect against a write access to the special registers so
