FEATURES
• Program memory (ROM): 4,074 × 10 bits
• Data memory (RAM): 128 × 4 bits
• On-chip carrier generator for infrared remote control: Each high-/low-level width can be set from 250 ns to 64
μs (@ fX = 4 MHz operation) via modulo registers
• 9-bit programmable timer: 1 channel
• Instruction execution time: 16 μs (normal instruction execution @ fX = 4 MHz operation)
8 μs (high-speed instruction execution @ fX = 4 MHz operation) (mask option)
