Actual value of the Half Buffer Transmitted Interrupt counter (incremented each time a Half
Buffer Transmitted Interrupt occurs)
When the 'ul_RpiCnt' value is incremented, new replay data should be reloaded to the
Shared RAM and should be copied from the Shared RAM to the Global RAM of the AIM
board area using thîs library function.
