Hello all,


I am working on a new project involving PDP and have questions in reference to the thread dealing with PDP. (Pulse Distance Protocol)


1. Using the TPM2 in OC Mode, do I need to deal with Timer Overflow? (I do not see any code in the thread to handle overflow)


2. In the TPM2 CH 0 ISR, the following code is used the load the value register:

          TPM2C0V += SPULSE;   // Start pulse (9000)


Is this code effectively the same as:

          TPM2C0V = TPM2CNT + SPULSE;   // Start pulse (9000)
