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 system reset. This is the default setting for
unprogrammed (erased) Flash.
WDT_AO—Watchdog Timer always On
0 = On application of system power, Watchdog Timer is automatically enabled. Watchdog
Timer cannot be disabled.
1 = Watchdog Timer is enabled on execution of the WDT instruction. Once enabled, the
Watchdog Timer is disabled only by a reset. This is the default setting 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 5.0 MHz).
11 = Maximum power for use with high frequency crystals (5.0 MHz to 20.0 MHz).
This is the default setting for unprogrammed (erased) Flash.
VBO_AO—Voltage Brownout protection always On
0 = VBO protection is disabled in STOP mode to reduce total power consumption.
1 = VBO protection is always enabled, even during STOP mode. This is the default setting
for unprogrammed (erased) Flash.
FRP—Flash 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
is the default setting for unprogrammed (erased) Flash.
