Write command
(/CS, /CAS, /WE = Low, /RAS = High)
If the mode register is in the burst write mode, this command sets the
burst start address given by the column address to begin the burst
write operation. The first write data in burst mode can input with this
command with subsequent data on following clocks.

Read command
(/CS, /CAS = Low, /RAS, /WE = High)
Read data is available after /CAS latency requirements have been
met. This command sets the burst start address given by the column
address.

CBR (auto) refresh command
(/CS, /RAS, /CAS = Low, /WE, CKE = High)
This command is a request to begin the CBR (auto) refresh
operation. The refresh address is generated internally.
Before executing CBR (auto) refresh, all banks must be precharged.
After this cycle, all banks will be in the idle (precharged) state and
ready for a row activate command.

command), the

PD45128xxx cannot accept any other command.
