Field
Description
0:25 Reserved (Read Only).
Write these bits has no effect and read these bits always outputs 0.

HSL5-0: High address space block SeLect 5-0 (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.
All the HSL5-0 are not used for both Code Flash 0 and 1 that are all mapped in mid and low address space.
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 HSL
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 both Code Flash 0 and 1, bits HSL5-0 are read-only and locked at 0.
0: High Address Space Block is unselected for Erase.
1: High Address Space Block is selected for Erase.

Figure 17-9. Address Register (ADR)
The Address Register provides the first failing address in the event module failures (ECC, RWW or FPEC)
or the first address at which a ECC single error correction occurs.
