WebCKE Input Clock Enable: CKE activates (HIGH) and deactivates (LOW) the CLK signal. If CKE goes low synchronously with clock (set-up and hold time same as other inputs), the internal clock is suspended from the next clock cycle and the state of output and burst address is frozen as long as the CKE remains low. Webof the CLK signal will be valid when is CKE HIGH and invalid when LOW. When CKE is LOW, the device will be in either power-down mode, clock suspend mode, or self refresh mode. CKE is an asynchronous input. CLK Input Pin CLK is the master clock input for this device. Except for CKE, all inputs to this device WebApr 13, 2024 · 1、搜索查找 DDR 控制器 IP。.
