*  8-bit version (188) is available for Am186ER (Not available for Am186Cx devices which feature an 8-bit boot option)

**  /2: Freq = Osc clock /2
      1x: Freq = Osc clock x1
      2x: Freq = Osc clock x2
      4x: Freq = Osc clock x4

***  Performance (MIPS) is tested by running Dhrystone 2.1 program, using zero waitstate memory (ex. 50 MHz w/50 ns memory)
