Addressing and Read/Write Mode Select
To access the SA8807A, a control byte has to be received first (after CE goes
active). This byte contains the information to initiate either a Read or Write mode
and an address.
The following bytes contain data until CE becomes inactive.
Address/Control Byte: The Address and Control Byte is the first byte sent after
CE goes active. To send another address, CE must first go inactive before going
active again. If the CE remains high, the device automatically increments the
address, for the following byte.
W/R = "1"
One or more write cycles to be sent.
W/R = "0"
Inititates one or more read cycles.
A5 - A0:
Address 5 to Address 0 selects the 6-bit HEX Address of RAM. (See LCD Character
