Register 14: EEPROM Current Block (EEBLOCK), offset 0x004
The EEBLOCK register is used to select the EEPROM block for subsequent reads, writes, and
protection control. The value is a block offset into the EEPROM, such that the first block is 0, then
second block is 1, etc. Each block contains 16 words. Attempts to set an invalid block causes the
BLOCK field to be configured to 0. To verify that the intended block is being accessed, software can
read the BLOCK field after it has been written. An invalid block can be either a non-existent block or
a block that has been hidden using the EEHIDE register. Note that block 0 cannot be hidden.

Reset Description
0x00000
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0x0000
Current Block
This field specifies the block in the EEPROM that is selected for
subsequent accesses. Once this field is configured, the read-write
registers operate against the specified block, using the EEOFFSET
register to select the word within the block. Additionally, the protection
and unlock registers are used for the selected block. The maximum
value that can be written into this register is determined by the block
count, as indicated by the EESIZE register. Attempts to write this field
larger than the maximum number of blocks or to a locked block causes
this field to be configured to 0.
