Introduction to C5545 BoosterPack Board
2.3
Reset Circuit and Distribution
All devices on the C5545 BoosterPack can be reset by the following:
•
BoosterPack on-board RESET button (SW1)
•
Power good signal from the DC-DC regulator
•
Software initiated reset by LaunchPad MCU on pin 5
•
Hardware initiated reset by LaunchPad's RESET button or debugger on pin 16
C5545 DSP can be reset independently by the XDS100 USB debugger.
CC2650 wireless MCU can be reset independently by the following:
•
Software initiated reset by C5545 DSP
•
Hardware initiated reset by external debugger on 10-pin JTAG header
NOTE: The SW1 (RESET) will only reset the C5545 BoosterPack and not the LaunchPad. The 1.8
V IO voltage on the C5545 is incompatible with the 3.3 V IO voltage on the MSP432
LaunchPad. All signals from MSP432 LaunchPad are connected to C5545 through level
translators because the MSP432 LaunchPad operates at 3.3 V IO.
