WDT_RES—Watchdog Timer Reset
0 = Watchdog Timer time-out generates an interrupt request. Interrupts must be globally
enabled for the eZ8 CPU to acknowledge the interrupt request.
1 = Watchdog Timer time-out causes a Short Reset. This setting is the default for unpro-
grammed (erased) Flash.
WDT_AO—Watchdog Timer Always On
0 = Watchdog Timer is automatically enabled upon application of system power. Watch-
dog Timer can not be disabled except during STOP Mode (if configured to power down
during STOP mode).
1 = Watchdog Timer is enabled upon execution of the WDT instruction. Once enabled, the
Watchdog Timer can only be disabled by a Reset or Stop Mode Recovery. This setting is
the default for unprogrammed (erased) Flash.
OSC_SEL[1:0]—Oscillator Mode Selection
00 = On-chip oscillator configured for use with external RC networks (<4 MHz).
01 = Minimum power for use with very low frequency crystals (32 kHz to 1.0 MHz).
10 = Medium power for use with medium frequency crystals or ceramic resonators
(0.5 MHz to 10.0 MHz).
11 = Maximum power for use with high frequency crystals (8.0 MHz to 20.0 MHz). This
setting is the default for unprogrammed (erased) Flash.
VBO_AO—Voltage Brownout Protection Always On
0 = Voltage Brownout Protection is disabled in STOP mode to reduce total power
1 = Voltage Brownout Protection is always enabled including during STOP mode.
RP—Read Protect
0 = User program code is inaccessible. Limited control features are available through
consumption.
This setting is the default for unprogrammed (erased) Flash.
