PWRDN Power Down control input. Active high. When the Power Down mode is set high, all internal analog functions are disabled to place the 73S8023C in its lowest power consumption mode. The Power Down mode is only allowed out of a card session (i.e. when CMDVCC = 1) Sets the divide ratio from the XTAL oscillator (or external clock input) to the card clock. -
