WDT_RES—Watch-Dog Timer Reset
0 = Watch-Dog Timer time-out generates an interrupt request. Interrupts must be globally
enabled for the eZ8 CPU to acknowledge the interrupt request.
1 = Watch-Dog Timer time-out causes a Short Reset. This setting is the default for unpro-
grammed (erased) Flash.
WDT_AO—Watch-Dog Timer Always On
0 = Watch-Dog Timer is automatically enabled upon application of system power. Watch-
Dog Timer can not be disabled.
1 = Watch-Dog Timer is enabled upon execution of the WDT instruction. Once enabled,
the Watch-Dog Timer can only be disabled by a Reset or Stop Mode Recovery. This set-
ting is the default for unprogrammed (erased) Flash.
Reserved
These Option Bits are reserved for future use and must always be set to 1. This setting is
the default for unprogrammed (erased) Flash.
RP—Read Protect
0 = User program code is inaccessible. Limited control features are available through the
On-Chip Debugger.
1 = User program code is accessible. All On-Chip Debugger commands are enabled. This
setting is the default for unprogrammed (erased) Flash.
