... DELAY any SRAM WRITE cycles requested after low will be inhibited until HSB During any STORE operation, regardless of how it was initiated, the STK14CA8 will continue to drive the pin low, releasing it only when the STORE HSB is complete. Upon completion of the STORE operation the STK14CA8 will remain disabled until the pin returns high ...
