2.8.17 Start Buffer Register F200h (R/W)
This Read/Write register describes the BufferRAM Sector Count (BSC) and BufferRAM Sector Address (BSA).
The BufferRAM Sector Count (BSC) field specifies the number of sectors to be loaded, programmed, or copy back programmed. At 00 value
(the default value), the number of sector is "4". If the internal RAM buffer reaches its maximum value of 11, it will count up to 0 value to meet
the BSC value. For example, if BSA = 1101, BSC = 00, then the selected BufferRAM will count up from '1101
The BufferRAM Sector Address (BSA) is the sector 0~3 address in the internal BootRAM and DataRAM where data is placed.
F200h, default = 0000h
NOTE :
In case of ’Cache Read’, BSA has to be set to 1000 or 1100. And BSC has to be set to 00.
In case of ’Synchronous Burst Block Read’, BSA has to be set to 1000 . And BSC has to be set to 00.
In case of ’2X Program’ or ’2X Cache Program’, BSA has to be set to 1000. And BSC has to be set to 00.
