Reset Value:
Offset:
• WDEN: Watch Dog Enable (Code Label WD_WDEN)
0 = Watch Dog is disabled and does not generate any signals.
1 = Watch Dog is enabled and generates enabled signals.
• RSTEN: Reset Enable (Code Label WD_RSTEN)
0 = Generation of an internal reset by the Watch Dog is disabled.
1 = When overflow occurs, the Watch Dog generates an internal reset.
• IRQEN: Interrupt Enable (Code Label WD_IRQEN)
0 = Generation of an interrupt by the Watch Dog is disabled.
1 = When overflow occurs, the Watch Dog generates an interrupt.
• EXTEN: External Signal Enable (Code Label WD_EXTEN)
0 = Generation of a pulse on the pin NWDOVF by the Watch Dog is disabled.
1 = When an overflow occurs, a pulse on the pin NWDOVF is generated.
• OKEY: Overflow Access Key (Code Label WD_OKEY)
Used only when writing WD_OMR. OKEY is read as 0.
0x234 = Write access in WD_OMR is allowed.
Other value = Write access in WD_OMR is prohibited.
