Note Shown above is the case when the self-refresh cycle is started in the IDLE or software STOP mode. If
the self-refresh cycle is started by inputting the active level of the SELFREF signal, SDCLK is output
without going low.
Remarks 1. The number of wait states set by the BCW1n and BCW0n bits of the SCRn register × 4 clocks
will be inserted in the BCW × 4 clk period.
2. n = 1, 3, 4, 6
