TC6387XB executes buffer-off for Input Signals from Host interface and SD Card by asserting #SUSPEND.
* Phase I:
Immediately after the power is turned ON, #PCLR indicates "L" whereas #SUSPEND indicates "H". All
the circuits are cleared in this state.
Assertion of #PCLR deactivated (H). Normal state.
Assert #SUSPEND to activate SUSPEND state. TC6387XB executes Anti-Penetration Process for Input
Signals in this state. Also, TC6387XB does not accept Host Interface transactions in this state.
Moreover, stopping HCLK can reduce the power consumption.
TC6387XB is brought back to normal state by deactivating assertion of #SUSPEND.
