Preliminary Technical Data
FEEDAT Register
FEEDAT is a 16-bit data register. This register holds the data
value for flash read and write commands.

FEEADR Register
FEEADR is a 16-bit address register used for accessing
individual pages of the 32 kB flash block. The valid address
range for a user is: 0x0000 – 0x77FF. this represents the 30 kB
flash user memory space. A read or write access outside this
boundary causes a data abort exception to occur.

FEESIGN Register
The FEESIGN register is a 24-bit MMR. This register is updated
with the 24-bit signature value after the signature command has
been executed. This value is the result of the linear feedback
shift register (LFSR )operation initiated by the signature
command.

Description
Read Protection.
Cleared by user to protect all code. – no JTAG read
accesses for protected pages if this bit is set.
Set by user to allow reading the code via JTAG.
Protection for Page 59 (0x00087600 – 0x000877FF. Set
by user to allow writing the Page 59. Cleared to
