Configuration Registers (CONFIG)
3.1 Introduction
This section describes the configuration registers, CONFIG1 and CONFIG2. The configuration registers
enable or disable these options:
3.2 Functional Description
The configuration registers are used in the initialization of various options. The configuration register
(CONFIG1) can be written once after each reset but CONFIG2 register can perform multiple write. All of
the configuration register bits are cleared during reset. Since the various options affect the operation of
the MCU, it is recommended that these registers be written immediately after reset. The configuration
registers are located at $001D and $001F. The configuration registers may be read at anytime.
