◆ SatCounter() [3/3]

SatCounter::SatCounter	(	unsigned	bits,
		uint8_t	initial_val = `0`

inlineexplicit

Constructor for the counter.

The explicit keyword is used to make sure the user does not assign a number to the counter thinking it will be used as a counter value when it is in fact used as the number of bits.

Parameters

bits	How many bits the counter will have.
initial_val	Starting value for the counter.
