  High-Performance RISC CPU:
  ? Only 33 single word instructions to learn
  ? All instructions are single cycle (1 ms) except for
  program branches which are two-cycle
  ? 12-bit wide instructions
  ? 8-bit wide data path
  ? Seven special function hardware registers
  ? Two-level deep hardware stack
  ? Direct, indirect and relative addressing modes for
  data and instructions
  ? Internal 4 MHz RC oscillator with programmable
  calibration
  ? In-circuit serial programming
  Peripheral Features:
  ? 8-bit real time clock/counter (TMR0) with 8-bit
  programmable prescaler
  ? Power-On Reset (POR)
  ? Device Reset Timer (DRT)
