Remarks 1. Values in parentheses indicate values when a write start address structure is located other than in the
internal high-speed RAM.
2. The above processing times are those during stabilized operation of the internal high-speed oscillator
(RSTS = 1).
3. RSTS: Bit 7 of the internal oscillation mode register (RCM)
