Data Memory Differences
1. Data memory size has increased to 256 from
192 by adding bank 2.
2. Bank 1 locations 0xF0 - 0xFF are now common
RAM locations across banks 0-3.
Peripheral Differences
1. 12-bit A/D replaces 8-bit A/D.
2. Master Synchronous Serial Port replace
Synchronous Serial Port.
3. USART adds 9-bit address mode to module.
4. Bandgap Voltage Reference added.
5. Low-voltage Detect Module added.
6. Selectable Brown-out Reset voltages added.
