3.1.2 Load Data Into Buffer Command
Load Data into Buffer command is a two-cycle command. Two sequential designated command activates this operation. Sequentially
writing 00E0h and 0000h to the boot partition [0000h~01FFh, 8000h~800Fh] will load one page to DataRAM0. This operation refers
to FBA and FPA. FSA, BSA, and BSC are not considered.
At the end of this operation, FPA will be automatically increased by 1. So continuous issue of this command will sequentially load data
in next page to DataRAM0. This page address increment is restricted within a block.
The default value of FBA and FPA is 0. Therefore, initial issue of this command after power on will load the first page of memory,
which is usually boot code.
