The SMC is able to automatically apply a set of “slow clock mode” read/write waveforms when
an internal signal driven by the SMC’s Power Management Controller is asserted because
CLK_SMC has been turned to a very slow clock rate (typically 32 kHz clock rate). In this mode,
the user-programmed waveforms are ignored and the slow clock mode waveforms are applied.
This mode is provided so as to avoid reprogramming the User Interface with appropriate wave-
forms at very slow clock rate. When activated, the slow mode is active on all chip selects.
