Peripheral Usage

If the hybrid controller is used in a single chip mode, the Bootloader uses only internal Data RAM
for data buffering.
The Bootloader does not initialize any device peripheral except SCI0, Port E and PLL. The PLL
multiplier is set to18, which equals the hybrid controller's operational frequency of 72MHz.
Before starting the application, SCI0 is disabled, but the PLL is not reprogrammed to its initial
state.
The Bootloader uses a statically-calculated SCI baud rate value. This value was calculated with
the assumption that the external Oscillator Frequency is 8MHz.
