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), thenumber 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
→
1110
→
1111
→
1100'.
The BufferRAM Sector Address (BSA) is the sector 0~3 address in the internal BootRAM and DataRAM where data is placed.
