3.5.3.4 Get Selected Status Command
Tx ->3E 58 04 04 A1 0 - - 0 0 - - CKL CKH
Rx ->80 0 n n B0 B1 B2 B3 ... Bn CKL CKH
The Get Selected Status command gets the selected status or results from the MSP-Gang programmer.
The following numbers (A1) are available. See the description of the MSPGANG_GetAPIStatus function
(Section 4.2.43) for details of the B0...Bn byte contents.
GET_APP_FLAGS 10
GET_LAST_STATUS 12
GET_LAST_ERROR_NO 14
3.5.3.5 Read From Gang Data Buffer Command
Tx -> 3E 49 4 4 T 0 - - n 0 - - CKL CKH
Rx -> 80 0 n n D1 D2 D3 D4 D5 D6 D7 D8...Dn CKL CKH
The MSP-GANG Programmer contains a temporary data buffer that can be used for writing data to and
reading data from each target device. The buffer size is 128 bytes for each target device – Buffer[8] [128];
T = Target device number, 1 to 8
n = Number of bytes taken from the Buffer[T-1] [..]
3.5.3.6 Write to Gang Data Buffer Command
Tx -> 3E 4A n+4 n+4 T 0 - - n 0 D1 D2...Dn CKL CKH
Rx -> ACK
Write bytes to selected target’s Buffer -> Buffer[8] [128]
T = Target device number, 1 to 8
n = Number of bytes written to Buffer[T-1] [..]
3.5.4 API Firmware Commands That Should Not be Used
3.5.4.1 Interactive Process Command
Tx -> 3E 46 n n D1 ... Dn CKL CKH
Rx -> 80 0 k k D1 ... Dk CKL CKH
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.
3.5.4.2 Erase Image Command
Tx -> 3E 33 4 4 0 0 0 0 CKL CKH
Rx -> B0 (In Progress)
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.

3.5.4.3 Read Info Memory From MSP-GANG Command
Tx -> 3E 41 4 4 A1 0 0 0 CKL CKH
Rx -> 80 0 80 80 D1 ... D128 CKL CKH
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.
3.5.4.4 Write to MSP-GANG Info Memory Command
Tx -> 3E 42 84 84 A1 0 80 0 D1 ... D128 CKL CKH
Rx -> ACK
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.
3.5.4.5 Verify Access Key Command
Tx -> 3E 44 4 4 0 0 0 0 CKL CKH
Rx -> ACK or NACK
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.
3.5.4.6 Write to Image Block Command
Tx -> 3E 43 n n A1 A2 A3 0 –6 0 D1 ... Dn-6 CKL CKH
Rx -> ACK or NACK
The Write to Image Block command loads the data bytes into the image buffer of the MSP-GANG. Do not
use this function in your application. Use MSP-GANG GUI and MSP-GANG DLL for writing data into the
internal image buffer.
3.5.4.7 Verify Image Check Sum Command
Tx -> 3E 45 08 08 A1 A2 A3 0 LL LH D1 D2 CKL CKH
Rx -> ACK or NACK
The Verify Image Check Sum command verifies the image check sum of all written image contents. Do
not use this function in your application. Use MSP-GANG GUI and MSP-GANG DLL for writing and
verifying data in the internal image buffer.
3.5.4.8 Read Image Header Command
Tx -> 3E 47 6 6 A1 A2 0 0 n 0 CKL CKH
Rx -> 80 0 n n D1 ... Dn CKL CKH
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.
3.5.4.9 Disable API Interrupts Command
Tx -> 3E 4C 4 4 R R R R CKL CKH
Rx -> ACK
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.

3.5.4.10 Display Message on LCD Display Command
Tx -> 3E 54 n+4 n+4 A1 A2 n 0 D1 ... Dn CKL CKH
Rx -> ACK
NOTE: Do not use this command. This command is used by the API-DLL and GUI only.
3.5.4.11 Set IO State Command
Tx -> 3E 4E 0C 0C VL VH 08 00 D1 D2 D3 D4 D5 D6 D7 D8 CKL CKH
Rx -> ACK
Modify static levels on the I/O pins (JTAG lines).
Vcc – V
CC
level in mV ( V
CC
= VH × 256 + VL)
D1 – Open destination buffer for output and transferred data for each target
0 = none
1 = TDI (target1 to target8)
2 = TDOI (target1 to target8)
3 = TMS (target1 to target8)
4 = RST (target1 to target8)
5 = BSL-RX (target1 to target8)
D2 – data transferred to the buffer above
b0 to b7 – target1 to target8
D3 – output enable bits: 0 = high impedance, 1 = output
b2 (0x04) – common RST – the same state for all eight targets (Note: if the RST buffer above is
selected, then this state is ignored)
b3 (0x08) – common TEST – the same state for all eight targets
b4 (0x10) – common TCK – the same state for all eight targets
b5 (0x20) – common TMS – the same state for all eight targets (Note: if the TMS buffer above is
selected, then this state is ignored)

selected, then this state is ignored)
b3 (0x08) – common TEST – the same level for all eight targets
b4 (0x10) – common TCK – the same level for all eight targets
