Flash Block Verified as Erased
The BLANK flag indicates that an Erase Verify command (RDARY1) has checked the flash block and
found it to be blank. The BLANK flag is cleared by writing a 1. BLANK is also automatically cleared by the
start of any new command. Writing a 0 has no effect.

This read-only bitfield is reserved and always has the value zero.
This read-only bitfield is reserved and always has the value zero.
Valid commands appear in the following table. Writing any other combination sets the ACCERR flag in the
USTAT register.
If an Erase Verify command has been requested, and the CCIF flag is set, then a zero in BLANK
indicates that the block is not erased.
Flash block verifies as erased.
