This register determines how the Flash interface logic will respond to reads and writes to the
FLASHDAT Register.

SFLE
Bit7
SFLE: Scratchpad Flash Memory Access Enable
When this bit is set, Flash reads and writes through the JTAG port are directed to the 128-
byte Scratchpad Flash sector. When SFLE is set to logic 1, Flash accesses out of the
address range 0x00-0x7F should not be attempted. Reads/Writes out of this range will yield
undefined results.
0: Flash access from JTAG directed to the Program/Data Flash sector.
1: Flash access from JTAG directed to the Scratchpad sector.
WRMD2-0: Write Mode Select Bits.
The Write Mode Select Bits control how the interface logic responds to writes to the FLASH-
DAT Register per the following values:
000:
ignored.
001:
FLASHADR register. FLASHADR is incremented by one when complete.
010:
containing the address in FLASHADR. The data written must be 0xA5 for the erase to occur.
FLASHADR is not affected. If FLASHADR = 0x7BFE - 0x7BFF, the entire user space will be
erased (i.e. entire Flash memory except for Reserved area 0x7C00 - 0x7FFF).
(All other values for WRMD2-0 are reserved.)
RDMD3-0: Read Mode Select Bits.
The Read Mode Select Bits control how the interface logic responds to reads to the FLASH-
DAT Register per the following values:
0000:
ignored.
0001:
if no operation is currently active. This mode is used for block reads.
0010:
operation is active and any data from a previous read has already been read from FLASH-
DAT. This mode allows single bytes to be read (or the last byte of a block) without initiating
an extra read.
(All other values for RDMD3-0 are reserved.)

Bit6
A FLASHDAT write replaces the data in the FLASHDAT register, but is otherwise
A FLASHDAT write initiates a write of FLASHDAT into the memory address by the
A FLASHDAT write initiates an erasure (sets all bytes to 0xFF) of the Flash page
A FLASHDAT read provides the data in the FLASHDAT register, but is otherwise
A FLASHDAT read initiates a read of the byte addressed by the FLASHADR register
A FLASHDAT read initiates a read of the byte addressed by FLASHADR only if no
