This register holds the address for all JTAG Flash read, write, and erase operations. This register autoincrements
after each read or write, regardless of whether the operation succeeded or failed.
Bits15-0: Flash Operation 16-bit Address.
This register is used to read or write data to the Flash memory across the JTAG interface.
Bits9-2:
Bit1:
Bit0:
Bit15
Bit9
DATA7-0: Flash Data Byte.
FAIL: Flash Fail Bit.
0: Previous Flash memory operation was successful.
1: Previous Flash memory operation failed. Usually indicates the associated memory location
was locked.
BUSY: Flash Busy Bit.
0: Flash interface logic is not busy.
1: Flash interface logic is processing a request. Reads or writes while BUSY = 1 will not
initiate another operation
