General-register machine

• Eight 16-bit general registers
• Five 8-bit and two 16-bit control registers High speed
• Maximum clock rate: 10MHz (oscillator frequency:  20MHz) Expanded operating modes supporting external memory
• Minimum mode: up to 64K-byte address space
• Maximum mode:  up to 1M-byte address space Highly orthogonal instruction set
• Addressing modes and data size can be specified independently for each instruction 1.5 Addressing modes •

  Register-register operations •

  Register-memory operations Instruction set optimized for C language •

 Special short formats for frequently-used instructions and addressing modes

Memory           •  1K-Byte high-speed RAM on-chip

                         32K-Byte programmable or masked ROM on-chip

16-Bit free-        Each channel provides:

 running            •  1 free-running counter (which can count external events)

 timer (FRT)      •  2 output-compare registers

(3 channels)      •  1 input capture register

 8-Bit timer       •  One 8-bit up-counter (which can count external events)

 (1 channel)      •  2 time constant registers

PWM timer      •  Generates pulses with any duty ratio from 0 to 100%

(3 channels)     •  Resolution:  1/250

 Watchdog       •  An overflow generates a nonmaskable interrupt

timer (WDT)    •  Can also be used as an interval timer (1 channel)
