Return values

midBlockSelect

To select the array blocks

in mid address space for

erasing.

Bit-mapped value such that the least significant

bit is at bit 0 of 16K block region (if available),

then 32K block region (if available) and lastly

64K block region (if available). Select the block

in the middle address space to be erased by

setting 1 to the appropriate bit of

midBlockSelect. If there is not any block to be

erased in the middle address space,

midBlockSelect must be set to 0.

highBlockSelect

To select the array blocks

in high address space for

erasing.

Bit-mapped value such that the least significant

bit is at bit 0 of 16K block region (if available),

then 32K block region (if available) and lastly

64K block region (if available). Select the block

in the high address space to be erased by

setting 1 to the appropriate bit of

highBlockSelect. If there is not any block to be

erased in the high address space,

highBlockSelect must be set to 0.

nLargeBlockSelect

To select the array blocks

address space for erasing.

It includes two elements to

decode the first half of

Large block select and the

second half of Large block

select.

Bit-mapped value such that the least significant

bit is at bit 0 of Large block region (if available).

Select the block in the Large address space to

be erased by setting 1 to the appropriate bit of

nLargeBlockSelect. If there is not any block to
