Bit15
WRMD3
This register determines how the Flash interface logic will respond to reads and writes to the
FLASHDAT Register.
Bits7-4: WRMD3-0: Write Mode Select Bits.
Bits3-0: RDMD3-0: Read Mode Select Bits.
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.

Bit7
The Write Mode Select Bits control how the interface logic responds to writes to the
FLASHDAT Register per the following values:
0000: A FLASHDAT write replaces the data in the FLASHDAT register, but is otherwise
0001: A FLASHDAT write initiates a write of FLASHDAT into the memory location
0010: A FLASHDAT write initiates an erasure (sets all bytes to 0xFF) of the Flash page
(All other values for WRMD3-0 are reserved.)
The Read Mode Select Bits control how the interface logic responds to reads to the
FLASHDAT Register per the following values:
0000: A FLASHDAT read provides the data in the FASHDAT register, but is otherwise
0001: A FLASHDAT read initiates a read of the byte addressed by the FLASHADR register
0010: A FLASHDAT read initiates a read of the byte addressed by FLASHADR only if no
(All other values for RDMD3-0 are reserved.)

containing the address in FLASHADR. FLASHDAT must be 0xA5 for the erase to
occur. FLASHADR is not affected. If FLASHADR = 0x7DFE – 0x7DFF, the entire
user space will be erased (i.e. entire Flash memory except for Reserved area 0x7E00 –
0x7FFF).

if no operation is currently active. This mode is used for block reads.
operation is active and any data from a previous read has already been read from
FLASHDAT. This mode allows single bytes to be read (or the last byte of a block)
without initiating an extra read.
