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 5.0 MHz).
11 = Maximum power for use with high frequency crystals (5.0 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 can be disabled in STOP mode to reduce total power
consumption. For the block to be disabled, the power control register bit must also be writ-
ten (see
Power Control Register Definitions
on page 34).
1 = Voltage Brownout Protection is always enabled including during STOP mode. This
setting is the default 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
setting is the default for unprogrammed (erased) Flash.
Reserved—Must be 1.
FWP—Flash Write Protect
This Option Bit provides Flash Program Memory protection:
0 = Programming and erasure disabled for all of Flash Program Memory. Programming,
Page Erase, and Mass Erase through User Code is disabled. Mass Erase is available using
the On-Chip Debugger.
1 = Programming, Page Erase, and Mass Erase are enabled for all of Flash program
memory.
