When SK is substantial degree and CS is modified from significant degree to reduced amount, AK6420A/40A/80A can receive theinstructions. CS ought to be stored minimal degree while receiving op-code, deal with and info and though outputting knowledge.If CS is modified to substantial amount in the course of the above period, AK6420A/40A/80A stops the instruction execution.When SK is small and CS is changed from superior amount to very low level, AK6420A/40A/80A will likely be in position outputmode.
The CS needn't be lower degree throughout the automated write time-out period (Hectic standing).SK (Serial Clock)The SK clock pin could be the synchronous clock enter for input/output knowledge.
At produce operation, AK6420A/40A/80Atakes within the publish facts from knowledge enter pin (DI) synchronously with climbing edge of enter pulse of serial clock pin(SK).
And at browse operation, AK6420A/40A/80A takes out the read through details to information output pin (DO)synchronously with falling fringe of SK.
The SK clock just isn't required all through the automated compose time-out period of time(Fast paced position), the position output interval and if the gadget is just not selected (CS = substantial amount).DI (Info Input)The op-code, handle and compose data is input for the DI pin.
DO (Details Output)The DO pin outputs the go through information and standing signal and will be superior impedance except for this timing.RDY/BUSY (Ready/Busy position)This pin outputs the internal programming standing.
When the AK6420A/40A/80A is while in the automated create time-out period, this pin outputs the lower stage (Fast paced position), and outputs the significant level except for this timing.
