Mask Option Register (MOR)
The mask option register (MOR) is implemented as a byte within the FLASH
memory, and therefore it is programmed using a FLASH memory byte-
programming operation. This register is read after a power-on reset to
determine the type of oscillator selected.
OSCSEL — Oscillator Select Bit
1 = Crystal oscillator
0 = RC oscillator
Configuration Registers (CONFIG1, CONFIG2)
The configuration registers are used to initialize various options. The
configuration registers can each be written once after each reset. Most of the
configuration register bits are cleared during reset. Since the various options
affect the operation of the microcontroller unit (MCU) it is recommended that
these registers be written immediately after reset. The configuration registers
are located at $001E and $001F, and may be read at anytime.
