Data Read
External HOST pull A0 low, while RSTS active high, it indicated that Data Buffer Memory is ready to be
read by external microprocessor through Data[0:15] port. HOST continues read 256 words data by bring
/CS is low. Data is latched on the rising edge of /RE. The GL824 Data Buffer Memory Address Pointer is
increased automatically. After data continues read operation is finished, RSTS is low. When GL824 Data
Buffer Memory is ready for HOST read data, RSTS return to high.
