MSP430F55x Demo - Port Map single function to multiple pins; Multiple runtime configurations

Description: The port mapping of TIMERB0 is changed with each WDT interrupt. TIMER_B0 provides 4 PWMs with 4 different duty cycles. TIMER_B0 is sourced from ACLK. ACLK is REFO, 32kHz

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• PMAP module
• GPIO Port peripheral
• UCS module
• Timer module

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• WDT_A_VECTOR
