CHAPTER 1 OUTLINE (µPD780078 SUBSERIES)
1.2 Features
• Minimum instruction execution time changeable from high speed (expanded-specification products 0.166 µs:
@ 12 MHz operation with main system clock, conventional products 0.238 µs: @ 8.38 MHz operation with main
system clock) to ultra-low speed (122 µs: @ 32.768 kHz operation with subsystem clock)
• General-purpose registers: 8 bits × 32 registers (8 bits × 8 registers × 4 banks)
• Internal memory
