Description
External Oscillator Mode Selection:
Reserved.
Minimum power for use with very low frequency crystals (32KHz to 1.0MHz).
Medium power for use with medium frequency crystals or ceramic resonators
(0.5MHz to 10.0MHz).
Maximum power for use with high frequency crystals (8.0MHz to 20.0MHz).
Voltage Brown Out Always On
Voltage Brown-Out Protection is disabled in STOP mode to reduce total power
consumption.
Voltage Brown-Out Protection is always enabled.

External access to User program code is disabled.
User program code is accessible.
Must be 1.
This Option Bit is reserved for future use and must always be 1.
Flash Write Protect
Programming, Page Erase, and Mass Erase using User Code is disabled.
Programming, Page Erase, and Mass Erase are enabled for all of Flash Program
Memory.
Program Memory Address 0001H
These bits define the behavior of the Pulse-Width Modulator. The high and low default
off-state (the output polarity) is also defined here. The off-state is used by the PWM output
control and PWM Fault logic. PWM output pairs can be disabled and used as high-imped-
ance input pins. The RESET/Fault0 pin function is also selectable.
