Command Write
Command, address and data are all written through Data[0:15] port by bring /WE to low, while A0 is high
and WSTS also pull high, it indicated that GL824 is ready for HOST write command. When /CS is low,
command is latched on the rising edge of /WE. When WSTS goes low it indicates that Command is latched
into command register by GL824.

Status Read
Register status, address and data can be read through Data[0:15] port by bring RE to low, while A0 is high
and RSTS also return high, it indicated that GL824 is ready for HOST read status. When /CS is low.
Register status latched on the rising edge of /RE. After status read operation is finished, RSTS is low.

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