This register is used to read or write data to the Flash memory across the JTAG interface.
Bits9–2: DATA7–0: Flash Data Byte.
Bit1:
Bit0:
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 17-bit Address.
Bit16
Bit9
JTAG Register Definition 25.5. FLASHADR: JTAG Flash Address
FAIL: Flash Fail Bit.
0: Previous Flash memory operation was successful.
1: Previous Flash memory operation failed. Usually indicates the associated memory loca-
tion 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 ini-
tiate another operation.
JTAG Register Definition 25.4. FLASHDAT: JTAG Flash Data
