Cautions
(1) Registers to be set first
Be sure to set the following registers first when using the V850ES/SG2 and V850ES/SG2-H.
System wait control register (VSWC)
On-chip debug mode register (OCDM)
Watchdog timer mode register 2 (WDTM2)
After setting the VSWC, OCDM, and WDTM2 registers, set the other registers as necessary.
When using the external bus, set each pin to the alternate-function bus control pin mode by using the port-
related registers after setting the above registers.
(a) System wait control register (VSWC)
The VSWC register controls wait of bus access to the on-chip peripheral I/O registers.
Three clocks are required to access an on-chip peripheral I/O register (without a wait cycle).
The
V850ES/SG2 and V850ES/SG2-H require wait cycles according to the operating frequency.
Set the
following value to the VSWC register in accordance with the frequency used. However, if fCLK is greater
than 20 MHz, only the V850ES/SG2-H can be used.
The VSWC register can be read or written in 8-bit units (address: FFFFF06EH, default value: 77H).

(b) On-chip debug mode register (OCDM)
For details, see CHAPTER 31 ON-CHIP DEBUG FUNCTION.
(c) Watchdog timer mode register 2 (WDTM2)
The WDTM2 register sets the overflow time and the operation clock of the watchdog timer 2.
The watchdog timer 2 automatically starts in the reset mode after reset is released. Write the WDTM2
register to activate this operation.
For details, see CHAPTER 11 FUNCTIONS OF WATCHDOG TIMER 2.
