Bytes in Packet
Transfers data and programs flash. Transferring
data which is programmed into flash following a
COMMAND_DOWNLOAD command or another
COMMAND_SEND_DATA command.
The number of data bytes to be programmed in
4 to 255 flash can be 1 to 252 (maximum data load in
packet).
If more data are downloaded by the
COMMAND_SEND_DATA commands than are
specified by the COMMAND_DOWNLOAD
command, an error status is generated.
Performs a system reset. See
3
Software-initiated System Reset, for details.
Erases one sector within the flash main bank. The
sector to erase is specified by the sector start
address. Only flash sectors not protected by write-
7 protect bits in FCFG1 and CCFG are erased.
If the top sector is selected (containing CCFG), the
content of CCFG will be reset to the same values
as when the devices was delivered from TI.
Calculates CRC32 over a specified memory area.
15 The number of reads per memory location is
specified.
Returns the 32-bit UserID from the AON_WUC
3 JTAGUSERCODE register with MSB first. The ID is
returned within a protocol packet.
Reads a specified number of elements with a
specified access width (8 bits or 32 bits) from a
9 specified memory-mapped start address. The
requested amount of data must be less than the
maximum size of a communication packet.
Writes the received data in accesses with a
specified width (8 or 32 bits) from a specified
10 to 255 memory-mapped start address. Data to be written
must be contained in same packet as the
command.
Performs an erase of all of the customer-accessible
flash sectors not protected by FCFG1 and CCFG
write-protect bits. No erase operation is performed
if the CCFG parameter BANK_ERASE_DIS is
3 cleared.
Because the top sector might be erased
(containing CCFG), the content of CCFG will be
reset to the same values as when the devices was
delivered from TI.
Writes the CC26xx- and CC13xx-defined CCFG
fields to the flash CCFG area with the values
received in the data bytes of this command.
11 This command abstracts the user from detailed
knowledge concerning which physical addresses
within the flash CCFG holding the defined CCFG
fields.
