17.2.6.9 High Address Space Block Select Register (HBS)
The High Address Space Block Select register provides a means to select blocks to be operated on during
erase.
14:15 MSL1-0: Mid address space block SeLect 1-0 (Read/Write)
A value of 1 in the select register signifies that the block is selected for erase.
A value of 0 in the select register signifies that the block is not selected for erase. The reset value for the
select register is 0, or unselected.
For Code flash 0, MSL1-0 are related to sectors B0F7-6, respectively.
For Code flash 1, MSL1-0 are related to sectors B2F3-2, respectively.
The blocks must be selected (or unselected) before doing an erase interlock write as part of the Erase
sequence. The select register is not writable once an interlock write is completed or if a high voltage
operation is suspended.
In the event that blocks are not present (due to configuration or total memory size), the corresponding MSL
bits will default to unselected, and will not be writable. The reset value will always be 0, and register writes
will have no effect.
0: Mid Address Space Block is unselected for Erase.
1: Mid Address Space Block is selected for Erase.
16:31 LSL15-0: Low address space block SeLect 15-0 (Read/Write)
A value of 1 in the select register signifies that the block is selected for erase.
A value of 0 in the select register signifies that the block is not selected for erase. The reset value for the
select register is 0, or unselected.
For Code flash 0, LSL5-0 are related to sectors B0F5-0, respectively.
For Code flash 1, LSL1-0 are related to sectors B2F1-0, respectively.
The blocks must be selected (or unselected) before doing an erase interlock write as part of the Erase
sequence. The select register is not writable once an interlock write is completed or if a high voltage
operation is suspended.
In the event that blocks are not present (due to configuration or total memory size), the corresponding LSL
bits will default to unselected, and will not be writable. The reset value will always be 0, and register writes
will have no effect.
In Code flash 0, bits LSL15-6 are read-only and locked at 0. In Code flash 1 bits LSL15-2 are read-only
and locked at 0.
0: Low Address Space Block is unselected for Erase.
1: Low Address Space Block is selected for Erase.
