Referenced by init_generics(), and init_registers().

sr_param<uint32_t> GPTimer::g_ntimers

Number of Counter in the Timer. For compatibility to the GPTimer VHDL model this is still called "timers". But keep in mind that the ticking units of the SystemC GPTimer are called GPCounters/counters to decrease confusion.
