SERIAL CONFIGURATION MAP
The serial bits will be read by the clock buffer in the following order:
All unused register bits (Reserved and N/A) should be desined as “Don’t Care”. It is expected that the controller will force all of these bits to a
“0” level.
All register bits labeled “Initialize to 0” must be written to zero during intialization. Failure to do so may result in a higher than normal operating
current. The controller will read back the last written value.
Byte 0: SDRAM Output active/inactive register
1 = enable; 0 = disable
NOTE:
Byte 1: SDRAM Output active/inactive register
1 = enable; 0 = disable
