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)
D4 – output level on all targets: 0 = LOW, 1 = HIGH
b2 (0x04) – common RST – the same level for all eight targets (Note: if the RST buffer above is
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
b5 (0x20) – common TMS – the same level for all eight targets (Note: if the TMS buffer above is
selected, then this state is ignored)
D5 – V
CC
enable bits to each targets
b0 to b7 – target1 to target8
D6 – I
CC
HI enable: 0 = disable, 1 = enable
D7 – spare
D8 – spare
Example 1
Generate a short RST pulse on target 1 only and force RST level LOW on targets 2 to 5 and RST level
HIGH on targets 6 and 7. V
CC
on targets 1 to 7 is 3.3 V ( 0x0CE4) and on target 8 is 0 V (disabled).
Tx -> 3E 4E 0C 0C E4 0C 08 00 04 60 00 00 7F 00 00 00 CKL CKH
