inputting Low level from the RST pin requires at least 16 machine cycles (main clock).
• An external reset does not require the oscillation stabilization wait time.
• If an external reset request is generated from the RST pin during writing by a transfer
Notes:
instruction (such as MOV), the reset cancel wait state is set after completion of the transfer
instruction, so writing is terminated normally. For a string instruction (such as MOVS), the
reset cancel wait state may be set before completion of transfer by a specified counter value.
• To return from stop mode, subclock mode, subsleep mode, or watch mode to main clock
mode using the external reset pin (RST pin), input the Low level for at least "oscillator's
oscillation time* + 100 µs + 16 machine cycles (main clock)".
*: The oscillation time for the oscillator is the period of time taken until its amplitude
reaches 90%. It takes several to dozens of ms for crystal oscillators, hundreds of µs to
several ms for FAR/ceramic oscillators, and 0 ms for external clocks.
