■ FEATURES
Clock
Built-in PLL clock frequency multiplication circuit
Selection of machine clocks (PLL clocks) is allowed among frequency division by 2 on oscillation clock
and multiplication of 1 to 8 times of oscillation clock (for 4 MHz oscillation clock, 4 MHz to 32 MHz)
Minimum execution time of instruction : 31.25 ns (when operating with 4-MHz oscillation clock and 8-time
multiplied PLL clock)
Instruction system best suited to controller
16 Mbytes CPU memory space
24-bit internal addressing
Wide choice of data types (bit, byte, word, and long word)
Wide choice of addressing modes (23 types)
Enhanced multiply-divide instructions with sign and RETI instructions
Enhanced high-precision computing with 32-bit accumulator
Instruction system compatible with high-level language (C language) and multitask
Employing system stack pointer
