Member Data Documentation

bool GPCounter::chain_run

Stores wether a timer is running in chain mode or not.

Referenced by chaining(), ctrl_write(), do_reset(), and start().

sc_core::sc_event GPCounter::e_wait

The event which implements the corefunctionality. It gets set by calculate() and ticking() is waiting with it.

See Also: calculate(); ticking()

Referenced by calculate(), stop(), and ticking().

sc_core::sc_time GPCounter::lasttime

The Time when lastvalue was set.

See Also: lastvalue

Referenced by do_reset(), start(), stop(), value_read(), and value_write().

unsigned int GPCounter::lastvalue

A defined value to calculate the value of the value register. It gets set whether a write of the value register happens or stop() gets executet

See Also: lasttime; stop()

Referenced by do_reset(), stop(), value_read(), and value_write().

bool GPCounter::m_pirq

The interrupt state of the counter. Might be get deprecated.

Referenced by ctrl_read(), ctrl_write(), and ticking().

unsigned int GPCounter::nr

The number of the counter. This variable is needed to calculate the right delay slot and to find the corresponding registers.

Referenced by calculate(), chaining(), ctrl_read(), ctrl_write(), cycletime(), do_reset(), nextzero(), start(), stop(), ticking(), value_read(), and value_write().

GPTimer* GPCounter::p

A pointer to the parent GPTimer. This is needed to acces common functions and register.

Referenced by calculate(), ctrl_read(), ctrl_write(), cycletime(), do_reset(), nextzero(), start(), stop(), ticking(), value_read(), and value_write().

bool GPCounter::stopped

Stores wether a timer is stoped or not.

Referenced by ctrl_write(), do_reset(), start(), stop(), value_read(), and value_write().
